- 3 x^{2} - 24 x - 45 = 0

x = - 3, x = - 5

Solution steps

- 3 x^{2} - 24 x - 45 = 0

Move

45

to the right side

- 3 x^{2} - 24 x = 45

Divide both sides by

- 3

\frac{- 3 x ^{2} - 24 x}{- 3} = \frac{45}{- 3}

x^{2} + 8 x = - 15

Rewrite in the form

(x + a)^{2} = b

(x + 4)^{2} = 1

For

the solutions are

f (x) = a, - a

Solve

x + 4 = 1 : x = - 3

Solve

x + 4 = - 1 : x = - 5

The solutions to the quadratic equation are:

x = - 3, x = - 5

5 t^{2} - 3 t - 14 = 0

4 x^{2} + 9 x - 100 = 0

x, 9 x^{2} + 12 x + 4 = 6

20 = 50 t - 5 t^{2}

y, x^{2} - x y + y^{2} = 7
