25=20x-4x^2
A.0

B.1

C.2

D.3

Answer 1

1 solution

Answer 2

@TjRoDz Don't give the answer... guide people to the answer

Answer 3

ok sorry

Answer 4

\(\Large -4x^2+20x=25\)
\(\Large -4x^2+20x-25=0\)
a= -4 b=20 c=-25
\(\Large D=b^2-4ac\)
\(\Large D=20^2-4*-4*-25=0\)
When D (the discriminant) is zero, the equation has 1 solution

Answer 5

ok
