4x^3-20x^2-25x
X(4X^2-20X-25)
USING THE QUADRATIC EQUATION:x+=+%28-b+%2B-+sqrt%28+b%5E2-4%2Aa%2Ac+%29%29%2F%282%2Aa%29+WE GET.
X=(20+-SQRT[-20^2-4*4*-25])/2*4
X=(2-+-SQRT[400+400])/8
X=(20+-SQRT800)/8
X=(20+-28.28)/8
X=(20+28.28)/8
X=48.28/8
X=6.035 ANSWER.
X=(20-28.28)/8
X=-8.28/8
X=-1.035 ANSWER.
