Full solution

Q. Factor.\newlinew2+8w+7w^2 + 8w + 7
  1. Identify Coefficients: Identify the coefficients of the quadratic expression.\newlineThe quadratic expression is w2+8w+7w^2 + 8w + 7. Here, the coefficient of w2w^2 (aa) is 11, the coefficient of ww (bb) is 88, and the constant term (cc) is 77.
  2. Find Multiplying Numbers: Determine two numbers that multiply to c(7)c (7) and add up to b(8)b (8). We need to find two numbers that multiply together to give 77 and add up to 88. The numbers 11 and 77 fit this requirement because 1×7=71 \times 7 = 7 and 1+7=81 + 7 = 8.
  3. Write Factored Form: Write the factored form using the two numbers found in the previous step.\newlineThe factored form of the quadratic expression is (w+1)(w+7)(w + 1)(w + 7) because these two binomials multiply to give the original quadratic expression.
