@jim_thompson5910 ....can you help ?

Answer 10

one way is to first multiply 5 and -6 (first and last terms) to get -30

then find two numbers that multiply to -30 and add to 7

these two numbers are 10 and -3

Answer 11

so you break 7n into 10n - 3n and you factor by grouping

Answer 12

5n^2+7n-6

5n^2+10n-3n-6

(5n^2+10n)+(-3n-6)

5n(n+2)+(-3n-6)

5n(n+2)-3(n+2)

(5n-3)(n+2)


This means 5n^2+7n-6 factors to (5n-3)(n+2)
