Question

factorise X square + X - 32 plz​

Answer 1

$x^{2} +x-32$ = 0

It Is In the form of $ax^{2} +bx+c=0$ ; where a=1, b=1, c= -32

By using quadratic formula i.e; x = -b ±$\sqrt{b^{2}-4ac }$ ÷ 2a

⇒ x = -1 ± $\sqrt{1^{2}-4(1)(-31) }$ ÷ 2(1)

⇒x = -1 ±  $\sqrt{1+124 }$ ÷ 2

⇒ ∴ x = -1 + $\sqrt{125} /2$  and  x = -1 - $\sqrt{ 125 }$$/2$ I Hope this helped you. plzz give me 5 stars if i really helped you.... Thank you.
