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
