4 x^{2} - 200 = - 20

x = 35, x = - 35

Decimal Notation

x = 6.70820 \dots, x = - 6.70820 \dots

Solution steps

4 x^{2} - 200 = - 20

Move

200

to the right side

4 x^{2} = 180

Divide both sides by

4

x^{2} = 45

For

x^{2} = f (a)

the solutions are

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

x = 45, x = - 45

45 = 35

- 45 = - 35

x = 35, x = - 35

2 y^{2} + 10 y = - 7

(x - 1) (x - 2) (x - 6) > 0

9 x^{2} - 9 x + 2

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

\frac{1 \cdot 1 0 ^{- 14}}{4.4 \cdot 10 - 4}
