Identify Coefficients: Identify the coefficients for y2, y, and the constant term in the quadratic expression y2+19y+18. The coefficient of y2 is 1 (a=1), the coefficient of y is 19 (b=19), and the constant term is 18 (y0).
Find Multiplying Numbers: Find two numbers that multiply to the constant term, c(18), and add up to the coefficient of y, b(19). The two numbers that satisfy these conditions are 1 and 18 because 1×18=18 and 1+18=19.
Write Factored Form: Write the quadratic expression y2+19y+18 as a product of two binomials using the numbers found in the previous step.The factored form is (y+1)(y+18).
