Full solution

Q. Factor.\newline2n2+17n+82n^2 + 17n + 8
  1. Identify coefficients: Identify the coefficients aa, bb, and cc in the quadratic expression 2n2+17n+82n^2 + 17n + 8 by comparing it to the standard form ax2+bx+cax^2 + bx + c.a=2a = 2, b=17b = 17, c=8c = 8
  2. Find numbers for multiplication: Find two numbers that multiply to aca*c (28=162*8 = 16) and add up to bb (1717).\newlineThe numbers that satisfy these conditions are 11 and 1616 because 116=161*16 = 16 and 1+16=171+16 = 17.
  3. Rewrite middle term: Rewrite the middle term 17n17n using the two numbers found in the previous step: 1n1n and 16n16n. The expression becomes 2n2+1n+16n+82n^2 + 1n + 16n + 8.
  4. Group terms into pairs: Group the terms into two pairs: 2n2+1n2n^2 + 1n and 16n+816n + 8.
  5. Factor out common factors: Factor out the greatest common factor from each pair.\newlineFrom the first pair (2n2+1n)(2n^2 + 1n), factor out nn: n(2n+1)n(2n + 1).\newlineFrom the second pair (16n+8)(16n + 8), factor out 88: 8(n+1)8(n + 1).
  6. Correct math error: Notice that there is a mistake in the previous step. The common factor for the second pair 16n+816n + 8 should be 88, but the term inside the parentheses should be (2n+1)(2n + 1) to match the first pair. This is a math error.
