Identify a, b, c: Identify a, b, and c in the quadratic expression m2+5m+4.The quadratic expression is in the form of ax2+bx+c. Here, a=1, b=5, and b0.
Find two numbers: Find two numbers that multiply to c(4) and add up to b(5). We need to find two numbers that when multiplied give us 4 and when added give us 5. The numbers 1 and 4 satisfy these conditions because 1×4=4 and 1+4=5.
Write factored form: Write the factored form using the two numbers found in Step 2.The factored form of the quadratic expression will be (m+1)(m+4), because these factors will multiply to give the original quadratic expression.
