Question

Solve 3x^2 = –30x + 24.
Its Quadratics, can someone work it out for me please? :)

Answer 1

Hey! Welcome to OpenStudy!

You you rearrange the whole thing to get the standard form \(3x^2 + 30x - 24 = 0\)

We can factor out \(3\) and get \(3(x^2 + 10x - 8) = 0\)

Divide both sides by \(3\) --- \(x^2 + 10x - 8 = 0\)

Answer 2

Now solve that using the quadratic formula.

Answer 3

\( \color{Black}{\Rightarrow x = \Large {-b \pm \sqrt{b^2 - 4ac} \over 2a}}\)
