Question

Find the zeroes of the quadratic polynomial Px) = x2 + x-12 and
verify the relationship between the zeroes and the coefficients.​

Answer 1

Step-by-step explanation:

x²+x-12

x²+3x-4x-12

x(x+3)-4(x+3)

(x-4)(x+3)

alpha +beta= -b/a

-3+4=-1/1

-1=-1

proved

alpha ×beta =c/a

-3×4=-12/1

-12=-12
