Question

Factorize the following polynomial, x^2+5x-36

Answer 1

Answer:

Step-by-step explanation:

= x^2 +5x-36

= x^2 +x(9-4) -36

= x^2+9x-4x-36

= x(x+9)-4(x+9)

= (x+9) (x-4)

Answer 2

$\longrightarrow \sf \purple{ {x}^{2 } + 5x - 36}$

$\longrightarrow \sf { {x}^{2 } -4x + 9x - 36}$

$\longrightarrow \sf { x (x-4) +9 (x-4)}$

$\longrightarrow \sf { (x+9)(x-4)}$
