Answer:
x=4 or x=−4
Step-by-step explanation:
Let's solve your equation step-by-step.
2x2=32
Step 1: Subtract 32 from both sides.
2x2−32=32−32
2x2−32=0
For this equation: a=2, b=0, c=-32
2x2+0x+−32=0
Step 2: Use quadratic formula with a=2, b=0, c=-32.
x=
−b±√b2−4ac
2a
x=
−(0)±√(0)2−4(2)(−32)
2(2)
x=
0±√256
4
x=4 or x=−4
Answer:
x=4 or x=−4
