Answer :
Let's solve your equation step-by-step.
x=4x2−8
Step 1: Subtract 4x^2-8 from both sides.
x−(4x2−8)=4x2−8−(4x2−8)
−4x2+x+8=0
For this equation: a=-4, b=1, c=8
−4x2+1x+8=0
Step 2: Use quadratic formula with a=-4, b=1, c=8.
x=−b±√b2−4ac2a
x=−(1)±√(1)2−4(−4)(8)2(−4)
x=−1±√129−8
x=18+−18√129 or x=18+18√129
Answer:
x=18+−18√129 or x=18+18√129
