23 = x^{2} + 7

x = 4, x = - 4

Solution steps

23 = x^{2} + 7

Switch sides

x^{2} + 7 = 23

Move

7

to the right side

x^{2} = 16

For

x^{2} = f (a)

the solutions are

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

x = 16, x = - 16

16 = 4

- 16 = - 4

x = 4, x = - 4

x, 432 = 3 x^{2}

X^{2} + 3 X + 2 = 0

12 x^{2} + 25 x = 7

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

(2 x + 1) (x + 7) = (x + 5) (3 x - 1)
