Factor the polynomial by factoring out the greatest common factor, 7x2 + 5 - x = 6x2 + 10
x = -5
Soultion:
→ 7 × 2 + 5 - x = 6 × 2 + 10
Multiply.
→ 14 + 5 - x = 12 + 10.
Combine like terms.
→ 19 - x = 24
Isolate x (I'm going to add x and subtract 24 from both sides to avoid changing signs)
Answer
→ = x = -5
