Answer:
x = 2
Step-by-step explanation:
3x² - 2x(x + 1) = x² + x - 6 ← distribute and simplify left side
3x² - 2x² - 2x = x² + x - 6
x² - 2x = x² + x - 6 ( subtract x² + x from both sides )
- 3x = - 6 ( divide both sides by - 3 )
x = 2
Step-by-step explanation:
3x^2-2x(x+1) = x^2 +x-6
3x^2−2x(+1)=x^2+xx−6
3x^2−2x^2−2x=x^2+x−6
3x^2−2x^2-2x=x^2+x−6
1x^2-2x=x^2+x-6
1x^2−2x=x^2+x−6
x^2−2x=x^2+−6
solution:
x=2
