Answer: the answer is x^2=10
Step-by-step explanation:
5-2x^2=-15
- step one {subtract 5 from both sides} {example- 5-2x^2-5=15-5
- step two {simplify} {example- -2x^2=-20
- step three {divide both sides by -2} {example- -2x^2 = -20
- {{disclaimer this is part of step three}} -2 -2
- step four {simplify} {example- x^2=10
