Using inverse operations x is √10
Step-by-step explanation:
Given the question as 5-2x²=-15
Eliminate 5 from each side of the equation
-5+5-2x²= -15-5
-2x²=-20
2x²=20 ----------------------------divide both sides by 2
2x²/2 =20/2
x²=10------------eliminate the square on the left side by introducing a square root on the right side of the equation
x=√10
