Answer:
x = 4, -10
Explanation:
step 1 - divide both sides of the equation by two
[tex]2(x+3)^2=98\\\\(x+3)^2 = 49[/tex]
step 2 - use square root of both sides
[tex](x+3)^2 = 49[/tex]
x + 3 = ± 7
step 3 - split this up into two equations to represent both positive and negative seven
x + 3 = 7
x + 3 = -7
step 4 - solve for both equations
* to solve these equations, subtract three from both sides
x + 3 = 7
x + 3 - 3 = 7 - 3
x = 4
x + 3 = -7
x + 3 - 3 = -7 - 3
x = -10
Therefore, the solution to the equation is x = 4, -10
