2b^2 + 3b -35

choose two terms such that their product is 2* -35 = -70 and sum is +3. So the numbers are 10 & -7

so 2b^2 + 3b -35 = 2b^2 + 10b-7b -35

                            = 2b (b+5) -7 (b+5)

                           = (b+5) (2b-7)

Please let me know if you have any questions and best me if you are satisfactory.
