Nick is solving the equation 3x2 = 20 – 7x with the quadratic formula. What values should he use for a, b, and c?
CPhill or Alan should be able to answer your question, but neither is online at this time.
3x2 = 20 – 7x rearrange as
3x2 + 7x - 20 = 0
And using the form ....... ax2 + bx + c = 0
a = 3
b= 7
c = -20
