2 (x + 1.5 x)^{2} - 7.5 = 0

x = 0.77459 \dots, x = - 0.77459 \dots

Solution steps

2 (x + 1.5 x)^{2} - 7.5 = 0

Move

7.5

to the right side

2 (x + 1.5 x)^{2} = 7.5

Divide both sides by

2

(x + 1.5 x)^{2} = 3.75

For

(g (x))^{2} = f (a)

the solutions are

g (x) = f (a), - f (a)

Solve

x + 1.5 x = 3.75 : x = 0.77459 \dots

Solve

x + 1.5 x = - 3.75 : x = - 0.77459 \dots

The solutions to the quadratic equation are:

x = 0.77459 \dots, x = - 0.77459 \dots

3 x^{2} - 3 x + 7 = 9 x + 3

x^{2} + 11 x + 11 = 0

u^{2} + u - 12 = 0

w^{2} - 5 w - 36 = 0

x, (x - 4) (2 x - 3) = 2 x^{2} + p x + 12
