Question
Solve the equation
Solve for a
Solve for h
a=0
Evaluate
h2a2×2=a2
Use the commutative property to reorder the terms
2h2a2=a2
Move the expression to the left side
2h2a2−a2=0
Substitute a=2h2−1,b=0 and c=0 into the quadratic formula a=2a−b±b2−4ac
a=2(2h2−1)0±02−4(2h2−1)×0
Simplify the expression
a=4h2−20±02−4(2h2−1)×0
Simplify the expression
