2(x+15)2+20=0

2 (x + 15) 2 + 20 = 0

x = - 20

Solution steps

2 (x + 15) \cdot 2 + 20 = 0

Multiply the numbers:

2 \cdot 2 = 4

4 (x + 15) + 20 = 0

Move

20

to the right side

4 (x + 15) = - 20

Divide both sides by

4

x + 15 = - 5

Move

15

to the right side

x = - 20

\frac{u}{- 5} = 5

y + 50 = \frac{y}{2} + 70

4 x + 7 = 10

a, 18 = a \cdot b^{2}

y - 32 = - 1
