Question

if A and B are the zeros of the polynomial x square - x minus 12​

Answer 1

Answer:

Hey Mate!!

${x}^{2} - x - 12 \\ = > {x}^{2} - 4x + 3x - 12 \\ = > x(x - 4) + 3(x - 4) \\ = > (x + 3)(x - 4)$

This means, (x + 3) and (x - 4) are factors of the polynomial.

•••••> x = (-3) OR x = 4 are the zeroes of the polynomial.

•••••> A = (-3)

B = 4
