Question

Solve 3x2 = –30x + 24

Answer 1

divide each term by 3

x^2 = -10x + 8

add 10x and -8 to both sides

x^2 + 10x - 8 = 0

Now we need to use the quadratic formula

Answer 2

whats the answer???

Answer 3

\[\Large \frac{{ - b \pm \sqrt {{b^2} - 4ac} }}{{2a}}\]

Answer 4

If a quadratic is of the form \(a{x^2} + bx + c = 0\) then you can plug the appropriate numbers into the quadratic formula (above) to solve.
