Question

If 2(x+3)^2=98 find x in this equation.

Answer 1

x = - 10, x = 4

Explanation:

Given

2(x + 3)² = 98 ( divide both sides by 2 )

(x + 3)² = 49 ( take the square root of both sides )

x + 3 = ±
`√(49)` = ± 7 ( subtract 3 from both sides )

x = - 3 ± 7

Thus

x = - 3 - 7 = - 10

x = - 3 + 7 = 4

Answer 2

x= 4 or -10
