4 x^{2} + 7 = 43

x = 3, x = - 3

Solution steps

4 x^{2} + 7 = 43

Move

7

to the right side

4 x^{2} = 36

Divide both sides by

4

x^{2} = 9

For

x^{2} = f (a)

the solutions are

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

x = 9, x = - 9

9 = 3

- 9 = - 3

x = 3, x = - 3

0.6 x^{2} + 2.3 x - 20 = 0

n^{2} - 2 n - 3 = 0

(1 - x) (4 - x) + 2 = 0

3 x^{2} + 12 x - 5 = 0

x^{2} - 9.6 x = 1.96
