Question

find the zeros of quadrilateral polynomial 5x²+8x-4 and verify the relationship between the zeros and the coefficient 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)

Answer 2

Answer:

Step-by-step explanation:

  5x²+ 8 x - 4

=5x² + (10-2) x - 4

=5x² + 10 x - 2 x - 4

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

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

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