Question

If alpha and beta are zeros of the polynomial x2 + x -12 then find the value of alpha 2 and beta 2

Answer 1

Answer:

Step-by-step explanation:

P(x) = x^2+x-12

Factorisation::

X^2 +x - 12. (Splitting middle term)

X^2+4x -3x -12

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

(X+4)(x-3) (zeroes)

Alpha = -4

Beta = +3

Alpha^2 + beta^2 = (-4^2) + (3^2)

====== 16 + 9 = 25

Ans 25.
