Full solution

Q. Factor.\newlined2+18d+17d^2 + 18d + 17
  1. Identify bb and cc: Identify bb and cc in the quadratic expression d2+18d+17d^2 + 18d + 17. Compare d2+18d+17d^2 + 18d + 17 with the standard quadratic form x2+bx+cx^2 + bx + c. Here, b=18b = 18 and c=17c = 17.
  2. Find product and sum: Find two numbers whose product is cc (17)(17) and whose sum is bb (18)(18). We need to find two numbers that multiply to 1717 and add up to 1818. Since 1717 is a prime number, the only factors of 1717 are 11 and 1717 itself. (17)(17)00 and (17)(17)11, which matches our requirements. Two numbers: 11, 1717.
  3. Write factored form: Write the factored form using the two numbers found in Step 22.\newlineThe factored form of the quadratic expression is (d+1)(d+17)(d + 1)(d + 17).
