Answer 2

-3(12c2 -13c -14)

Answer 3

12c2 -13c -14=0

- so there us quadratic formula to solve this quadratic equation and than using these solutions you can writing this easy factorized

Answer 4

c_1,_2=(13+/- 29)/24 = - 16/24 = - 2/3 and 42/24 = 7/4

than this equation will be factorized like (3c+2)(4c-7)

Answer 5

hope that is understandably sure

Answer 6

good luck bye

Answer 7

so yes this is true that the first term before parantheses will be 3

Answer 8

than exctly is 3(3c+2)(4c-7)

Answer 9

ok ?
