Question

Factorise x^2+5x-36
we have to solve it by mid-term split

Answer 1

Step-by-step explanation:

$\mapsto{\sf{x^2+5x-36=0   }}$      

$\mapsto{\sf{x^2+9x-4x-36=0   }}$      

$\mapsto{\sf{ x(x+9)-4(x+9)=0  }}$      

$\mapsto{\sf{ (x+9)(x-4)=0  }}$      

$\mapsto{\sf{x+9=0~or~x-4=0   }}$      

$\mapsto{\bold{x=-9~or~x=4   }}$
