Question

2x² + 8x + 8 zeroes of polynomial

Answer 1

Answer:

Two zeroes of the polynomial are -2 and -2.

Step-by-step explanation:

Given polynomial, 2x² + 8x + 8.

For finding zeroes, we put the polynomial equal to 0.

.·.  2x² + 8x + 8 = 0.

    2(x² + 4x + 4) = 0.

    x² + 4x + 4 = 0.

    x² + 2x + 2x + 4 = 0.

    x(x+2) + 2(x+2) = 0.

    (x+2)(x+2) = 0.

    x+2 = 0 or  x+2 = 0.

    x = -2 or x = -2.
