Question

POLYNOMIALS
EXERCISE 2.2
1. Find the zeroes of the following quadratic polynomials and verify the relationship betwe
the zeroes and the coefficients.

(iv) 4u2 +8u
​

Answer 1

To find its zero, we have to equate it with zero

4u² + 8u = 0

4u(u+2) = 0

Either 4u = 0 or u+2 =0

therefore, either u = 0 or u = -2

Answer: 0 or -2
