Identify Coefficients: Identify the coefficients of the quadratic expression.The quadratic expression is j2+4j+3. Here, the coefficient of j2(a) is 1, the coefficient of j(b) is 4, and the constant term (c) is 3.
Find Multiplying Numbers: Find two numbers that multiply to c(3) and add up to b(4). We need to find two numbers that multiply together to give 3 and add together to give 4. The numbers 1 and 3 satisfy these conditions because 1×3=3 and 1+3=4.
Write Factored Form: Write the factored form using the two numbers found in the previous step.Since the numbers 1 and 3 satisfy the conditions, the factored form of the quadratic expression j2+4j+3 is (j+1)(j+3).
