Full solution

Q. Factor.\newline6x3+6x27x76x^3 + 6x^2 - 7x - 7
  1. Identify Common Factors: Look for common factors in the first two terms and the last two terms separately.\newlineWe can factor out 6x26x^2 from the first two terms and 7-7 from the last two terms.\newline6x3+6x27x7=6x2(x+1)7(x+1)6x^3 + 6x^2 - 7x - 7 = 6x^2(x + 1) - 7(x + 1)
  2. Factor Out Common Terms: Check if there is a common binomial factor from the two groups.\newlineBoth groups have a common factor of (x+1)(x + 1).\newline6x2(x+1)7(x+1)=(6x27)(x+1)6x^2(x + 1) - 7(x + 1) = (6x^2 - 7)(x + 1)
  3. Find Common Binomial Factor: Verify that the factored form is correct by expanding it to see if it matches the original polynomial.\newline(6x27)(x+1)=6x3+6x27x7(6x^2 - 7)(x + 1) = 6x^3 + 6x^2 - 7x - 7
