Question

Factorize the following by splitting the middle term . 1. X^2+10x+21 . 2. Y^2+18y+77. 3.x^2+9x+18. 4.6x^2+7x-3

Answer 1

X²+10x+21
x²+7x+3x+21
x(x+7)+3(x+7)
(x+3)(x+7)
=================================================
Y²+18y+77
y²+11y+7y+77
y(y+11)+7(y+11)
(y+11)(y+7)
=================================================
.x²+9x+18
x²+6x+3x+18
x(x+6)+3(x+6)
(x+6)(x+3)
=================================================
6x²+7x-3
6x²+9x-2x-3
3x(2x+3)-1(2x+3)
(2x+3)(3x-1)
====================================================
