Question

Find the zeroes of the polynomial 5x2 + 8x - 4 and verify the relationship between the

zeroes and the coefficients of the polynomial.​

Answer 1

Step-by-step explanation:

5 x^2 + 8 x - 4

=5 x^2 + (10-2) x - 4

=5 x^2 + 10 x - 2 x - 4

=5 x (x+2) -2(x+2)

=(x+2) (5 x -2)

So the zeros are (x+2) and (5 x -2)
