2 x^{2} - 5 = 8

x = \frac{13}{2}, x = - \frac{13}{2}

Solution steps

2 x^{2} - 5 = 8

Move

5

to the right side

2 x^{2} = 13

Divide both sides by

2

x^{2} = \frac{13}{2}

For

x^{2} = f (a)

the solutions are

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

x = \frac{13}{2}, x = - \frac{13}{2}

3 x^{2} + 6 x - 18 = 0

3 x^{2} - 2 = 2 x - 1

(x - 4)^{2} = (3 - x) (1 + 2 x)

t, e = \frac{1}{2} a t^{2}

9 x^{2} - 73 x + 73 = 0
