Question

Pleaseeee help!!!!!!!!!!!!!!!!

Answer 1

Answer:

A:- This polynomial has a degree of 2, so the equation x^2+x-12=0 has exactly 2 roots.

B:-The quadratic equation x^2+x-12=0 has two real solutions, x= 3 or x= -4

Step-by-step explanation:

1) A quadratic equation always has 2 real roots.

2) Solving the equation,

factorisation method,

x^2+x-12=0

x^2-3x+4x-12=0

x (x-3) +4 (x-3)=0

(x-3)(x+4)=0

thus x=3 or x=-4
