Transcript Both of them are negative. In this kind of case again you’re going to consider the signs again. Okay? Very very carefully be very careful. Now this time again I’m going to put my xs is on my left because it doesn’t really change x squared is x times x. I’m going to always […]

# Factorising Monic Quadratic Trinomials Minus Plus Form

Transcript Again I’m going to put x and x on the left-hand side because again x times x is definitely x squared. Now 3, 3 is simply 3 and 1, isn’t it? 3 times 1 is 3. But when this is a plus and this is a negative we need to make negative don’t we? […]

# Factorising Monic Quadratic Trinomials Plus Plus Form

# Algebraic Fractions: Addition and Subtraction

So what do I have to multiply to 11 to make 66, 6 isn’t it? So we have to multiply this denominator by 6.But guys, remember you can’t just multiply the denominator by six if you’re doing something to the bottom, you must do the same thing to the numerator to the top.So I’m going to […]

# Factorise using Double Common Factors

Transcript What I’m gonna do whenever you have four terms, I’m gonna try to group them into twos okay? So I just put like in just think those brackets are invisible. I’m just going to put brackets in there, so I’m going to do factorize this by individually and this individually. So I’m going to […]

# Factorise Common Factors in Brackets and Indices

Transcript Factorize a plus b squared minus 2a plus b. All right, so you can see that a plus b is common. Because this is one term and this is another. So a plus b is common in those two terms. Now what I’m going to do is separate a plus b squared because some […]

# Factorise Common Factors in Brackets

Transcript This term and this term what is common? What is the common factor? Can you guys see that a plus b is it in both of them? So a plus b is common. So we take the a plus b out the front like that. So we took a plus b, so we just […]

# Factorise using Common Factors and Indices

Transcript Again guys what I’m going to do is trying to expand that out in an expansion in expanded form. So I’ve got one we’ve got two b’s because it’s b squared so I put bb and three c, so ccc, because it’s c cubed right? I just put it like that you don’t have […]

# Factorise using Common Factors

Transcript Guys in these questions you have to ask yourself what is common? Or what is the common factor? Okay? Factor is the keyword here when you’re factorizing that’s why it’s factorizing okay? So in 2a and ab what is the common factor? What is common? So what’s commonly ask yourself what’s common.See how they […]

# Expand and Simplify Trinomial Expressions

Transcript Because it’s got three inside each of the brackets, so what I’m gonna do is times this massive bracket and then minus b times the bracket and c times the bracket as well, so we do it three times because we have three pre-numbers at the front, times that minus b times that plus […]
