1/8x^2=x-5/2
multiply each term by 8
x^2 = 8x - 20
x^2 - 8x + 20 = 0
You MUST know how to do the rest
(A)Write the equation in standard form and calculate its discriminant. (B)Solve the equation by using the quadratic formula. (C)After solving the equation, write it in factored form. 1/8x^2=x-5/2 Please help!!!!! :(

betting not :)
1x^2 -8x +20 = 0
if a =1, b=- 8 and c=20
and the discriminant is b^2 - 4ac sub in your values : )
