Question:

Solve the following equation: 2x^2 - 32 = 0

Lashaun S.
Answer:

Step one: Isolate the variable a. Add 32 to both sides and simplify 2x^2 - 32 + 32 = 0 + 32 2x^2 = 32 b. Divide both by 2 and simplify 2x^2/2 = 32/2 x^2=16 Step two: Solve for x by taking the square root of both sides sqrt(x^2) = sqrt(16) x=4 or x= -4
