How do I factorize a quadratic expression ?
Xelga [282]

Answer:

Please check below the step-by-step explanation.

Step-by-step explanation:

Considering the quadratic expression

ax^2+bx\:+\:c\:=0

a,\:b,\:and\:c\:can\:have\:any\:value,\:except\:that\:a\:can't\:be\:0.

To\:Factorise\:a\:Quadratic\:is\:to:

" find\:what\:to\:multiply\:to\:get\:the\:Quadratic "

For example, multiplying (x + 3) and (x - 2) together will bring x^2+x-6

i.e.

\left(x+3\right)\left(x-2\right) = xx+x\left(-2\right)+3x+3\left(-2\right)

\mathrm{Apply\:minus-plus\:rules}

+\left(-a\right)=-a

\left(x+3\right)\left(x-2\right) = xx-2x+3x-3\cdot \:2

                       = x^2+x-6

Therefore,  (x + 3) and (x - 2) are factors of x^2+x-6
