Solve the equation
Solve for a
Solve for b
a=0
Evaluate
a×ab×b=4a×a
Multiply
More Steps
Evaluate
a×ab×b
Multiply the terms
a2b×b
Multiply the terms
a2b2
a2b2=4a×a
Multiply the terms
a2b2=4a2
Rewrite the expression
b2a2=4a2
Add or subtract both sides
b2a2−4a2=0
Substitute a=b2−4,b=0 and c=0 into the quadratic formula a=2a−b±b2−4ac
a=2(b2−4)0±02−4(b2−4)×0
Simplify the expression
a=2b2−80±02−4(b2−4)×0
