Answer:

x = -0.441 and x = -2.359

Explanation:

The given equation is :


2(5x+7)^2-13=33

Adding 13 to both sides of the equation.


2(5x+7)^2-13+13=33+13\\\\2(5x+7)^2=46\\\\(5x+7)^2=23

So,


5x+7=√(23)\\\\5x+7=\pm4.795\\\\5x=4.795-7, 5x=-4.795-7\\\\5x=-2.205, 5x = -11.795\\\\x=-0.441, x=-2.359

So, the solution of the given equation is x = -0.441 and x = -2.359.
