Answer 2

${\tt{\pink{\underline{\underline{\huge{QUESTION:}}}}}}$

Factorise the x²+7x+ 12

${\tt{\pink{\underline{\underline{\huge{Answer:}}}}}}$

$\longrightarrow$ x²-7x-30

$\longrightarrow$ x²-(10+3)x-30

$\longrightarrow$ x²-10x+3x-30

$\longrightarrow$ x(x-10)+3(x-10)

$\longrightarrow$ (x-10)(x+3)
