Factorisation

[Dan Glebitts]

How do i factorize x2 + 10x + 24? when i say x2 i mean x squared

[scotstone]

This is a quadratic expression which may be factorised into two binomial terms i.e. (x+6)(x+4).

[wideboy]

(x+6) x (x+4)

The second x being multiply

[kempie]

In this example you need to find the factors of 24 which when added together give 10 (the x term), namely 6 & 4.

i.e. 6x4 = 24 and 6+4 = 10

therefore the answer is (x+6)(x+4)


If the equation had been x� + 10x - 24 you would need to find the factors of 24 which have a difference of 10 - 12 & 2.

i.e. 12x-2 = -24 and 12-2=10 which gives (x+12)(x-2)

cheers...hey u couldnt help me with this aswell? hence solve....x2 + 10x + 24 =0

[scotstone]

(x+4)(x+6)=O If the product of two numbers is zero then one of them must be zero therefore either x+4= 0and x= -4 or x+6=0 and x= -6
