Identify coefficients: Identify the coefficients a, b, and c in the quadratic expression 2g2+9g+10 by comparing it to the standard form ax2+bx+c.a=2, b=9, c=10
Find two numbers: Find two numbers that multiply to a∗c (2∗10=20) and add up to b (9).The numbers 5 and 4 multiply to 20 and add up to 9.
Rewrite middle term: Rewrite the middle term 9g using the two numbers found in the previous step: 5g and 4g. The expression becomes 2g2+5g+4g+10.
Factor by grouping: Factor by grouping. Group the first two terms and the last two terms separately.(2g2+5g)+(4g+10)
Factor out common factor: Factor out the greatest common factor from each group. g(2g+5)+2(2g+5)
Final factorization: Since both groups contain the common factor (2g+5), factor it out.(g+2)(2g+5)
