Identify Coefficients: Identify the coefficients of the quadratic expression.The quadratic expression is w2+8w+7. Here, the coefficient of w2 (a) is 1, the coefficient of w (b) is 8, and the constant term (c) is 7.
Find Multiplying Numbers: Determine two numbers that multiply to c(7) and add up to b(8). We need to find two numbers that multiply together to give 7 and add up to 8. The numbers 1 and 7 fit this requirement because 1×7=7 and 1+7=8.
Write Factored Form: Write the factored form using the two numbers found in the previous step.The factored form of the quadratic expression is (w+1)(w+7) because these two binomials multiply to give the original quadratic expression.
