Factor. u^2 + 7u + 10 ____

Identify Coefficients: Identify the coefficients of the quadratic expression. The quadratic expression is u^2 + 7u + 10. Here, the coefficient of u^2 (a) is 1, the coefficient of u (b) is 7, and the constant term (c) is 10.Find Multiplying Numbers: Determine two numbers that multiply to the constant term (c) and add up to the coefficient of u (b). We need to find two numbers that multiply to 10 and add up to 7. The numbers 2 and 5 satisfy these conditions because 2 * 5 = 10 and 2 + 5 = 7.Write Factored Form: Write the factored form using the two numbers found in the previous step. The factored form of the quadratic expression is (u + 2)(u + 5), since these two binomials multiply to give the original quadratic expression.
