5 x^{2} - 7 x - 90 = 0

x = - \frac{18}{5}, x = 5

Decimal Notation

x = - 3.6, x = 5

Solution steps

5 x^{2} - 7 x - 90 = 0

Factor

5 x^{2} - 7 x - 90 : (5 x + 18) (x - 5)

(5 x + 18) (x - 5) = 0

Using the Zero Factor Principle:

ab = 0

then

a = 0

b = 0

5 x + 18 = 0 or x - 5 = 0

Solve

5 x + 18 = 0 : x = - \frac{18}{5}

Solve

x - 5 = 0 : x = 5

The solutions to the quadratic equation are:

x = - \frac{18}{5}, x = 5

- 6 x^{2} + 7 x = 3 x - 8

- 6 x^{2} - 3 x + 6 = 0

x^{2} + 8 x + 15 = (x + 3)

(2 x + 3)^{2} = (x - 2)^{2}

x^{2} + 9^{2} = 1 2^{2}
