MEDAL AND FANS AWARDED
help please i dont understand this? The equations only has 2 variables and i thought a quadratic equation requires 3 variables?
Use the quadratic formula to solve -6x^2 + 6x = 0

Answer 1

terms you mean not variables. there is only one variable in your equation thats x

Answer 2

a quadratic equation can have only 2 terms
-6x^2 + 6x = 0

here a = -6, b = 6 and c = 0

so plug these values in to the formula and work out the roots

Answer 3

how do you do that though?

Answer 4

x = [-b +/- sqert(b^2 -4ac) ] / 2a

=[ -6 - sqrt(36 - 4*0*-6) [/ -12

=[ -6 - sqrt36] / 2 = -12 / 2 = -6

and the other value of x is

[- 6 + 6] / 2 = 0
