Identify coefficients: Identify the coefficients a, b, and c in the quadratic expression 2n2+17n+8 by comparing it to the standard form ax2+bx+c.a=2, b=17, c=8
Find numbers for multiplication: Find two numbers that multiply to a∗c (2∗8=16) and add up to b (17).The numbers that satisfy these conditions are 1 and 16 because 1∗16=16 and 1+16=17.
Rewrite middle term: Rewrite the middle term 17n using the two numbers found in the previous step: 1n and 16n. The expression becomes 2n2+1n+16n+8.
Group terms into pairs: Group the terms into two pairs: 2n2+1n and 16n+8.
Factor out common factors: Factor out the greatest common factor from each pair.From the first pair (2n2+1n), factor out n: n(2n+1).From the second pair (16n+8), factor out 8: 8(n+1).
Correct math error: Notice that there is a mistake in the previous step. The common factor for the second pair 16n+8 should be 8, but the term inside the parentheses should be (2n+1) to match the first pair. This is a math error.
