x^{2} - 10 x = 7

x = 42 + 5, x = - 42 + 5

Decimal

x = 10.65685 \dots, x = - 0.65685 \dots

Solution steps

x^{2} - 10 x = 7

Rewrite in the form

(x + a)^{2} = b

(x - 5)^{2} = 32

For

the solutions are

f (x) = a, - a

Solve

x - 5 = 32 : x = 42 + 5

Solve

x - 5 = - 32 : x = - 42 + 5

The solutions to the quadratic equation are:

x = 42 + 5, x = - 42 + 5

x, 9 x = - 8

x, ∣ x + 4 ∣ = ∣ x - 5 ∣

x^{2} - 4 x = 21

- 19 \cdot - 19
