2 x^{2} + 3 x = 9

x = \frac{3}{2}, x = - 3

Decimal Notation

x = 1.5, x = - 3

Solution steps

2 x^{2} + 3 x = 9

Move

9

to the left side

2 x^{2} + 3 x - 9 = 0

Factor

2 x^{2} + 3 x - 9 : (2 x - 3) (x + 3)

(2 x - 3) (x + 3) = 0

Using the Zero Factor Principle:

ab = 0

then

a = 0

b = 0

2 x - 3 = 0 or x + 3 = 0

Solve

2 x - 3 = 0 : x = \frac{3}{2}

Solve

x + 3 = 0 : x = - 3

The solutions to the quadratic equation are:

x = \frac{3}{2}, x = - 3

40 = 2 x^{2} + 2 x

x^{2} - 180 = 0

2 u^{2} - 5 u + 2 = 0

x^{2} - 22 x - 7 = 0

2 x^{2} = 6 + x
