2 (m - 10)^{2} - 30 = 0

m = 15 + 10, m = - 15 + 10

Decimal Notation

m = 13.87298 \dots, m = 6.12701 \dots

Solution steps

2 (m - 10)^{2} - 30 = 0

Move

30

to the right side

2 (m - 10)^{2} = 30

Divide both sides by

2

(m - 10)^{2} = 15

For

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

the solutions are

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

Solve

m - 10 = 15 : m = 15 + 10

Solve

m - 10 = - 15 : m = - 15 + 10

The solutions to the quadratic equation are:

m = 15 + 10, m = - 15 + 10

2 x^{2} - 8 x - 4 = 3 x - x^{2}

x, x^{2} - 3 x - 18 = 0

200 x^{2} = 100

x^{2} - 100 = 21

(k + 7)^{2} = 81
