Full solution

Q. Factor.\newline2g2+7g+52g^2 + 7g + 5
  1. Identify aa, bb, cc: Identify aa, bb, and cc in the quadratic expression 2g2+7g+52g^2 + 7g + 5 by comparing it with the standard form ax2+bx+cax^2 + bx + c.\newlinea=2a = 2\newlineb=7b = 7\newlinebb00
  2. Find two numbers: Find two numbers that multiply to aca*c (which is 25=102*5=10) and add up to bb (which is 77).\newlineThe two numbers that satisfy these conditions are 22 and 55 because:\newline2×5=102 \times 5 = 10\newline2+5=72 + 5 = 7
  3. Rewrite middle term: Rewrite the middle term of the quadratic expression using the two numbers found in Step 22.\newline2g2+7g+52g^2 + 7g + 5 can be rewritten as 2g2+2g+5g+52g^2 + 2g + 5g + 5 by splitting the middle term.
  4. Factor by grouping: Factor by grouping. Group the first two terms together and the last two terms together.\newline(2g2+2g)+(5g+5)(2g^2 + 2g) + (5g + 5)\newlineNow, factor out the common factors from each group.\newline2g(g+1)+5(g+1)2g(g + 1) + 5(g + 1)
  5. Factor out common binomial: Factor out the common binomial factor (g+1)(g + 1).\newlineThe factored form of the expression is (2g+5)(g+1)(2g + 5)(g + 1).
