x−8x2−64=64−x217(x+8)
To solve this problem, follow these steps:
- Step 1: Factorize the terms involving squares. Notice that x2−64=(x−8)(x+8) and 64−x2=(8−x)(8+x).
- Step 2: Rewrite both sides of the equation using these factorizations:
x−8(x−8)(x+8)=(8−x)(8+x)17(x+8)
Upon simplifying, the left side becomes x+8 because the (x−8) term cancels out, as long as x=8.
x+8=−(x−8)(x+8)17(x+8)
- Step 3: Cancel (x+8) from both numerator and denominator on the right side (assuming x=−8).
- Step 4: This simplifies to:
x+8=x−8−17
- Step 5: Multiply both sides by (x−8) to eliminate the denominator:
(x+8)(x−8)=−17
x2−64=−17
- Step 6: Rearrange and solve for x:
x2=47
x=±47
Therefore, the solution to the problem is x=±47.
