Question

1.Factor

3x(y−4)−2(y−4)

2. Factor.

20xy−4y+35x−7

Please Help!!! I'm trying to get caught up as fast as i can but k12 has been giving me so much work I can't keep up!!

Answer 1

(1)

take out the common factor (y - 4 )

= (y - 4)(3x - 2)

(2)

factor by grouping (1/2 terms and 3/4 terms )

4y(5x - 1) + 7(5x - 1)

take out the common factor (5x - 1)

= (5x - 1)(4y + 7)

Answer 2

1. Factor out the (y-4)

(y-4) (3x-2)

2.Factor by grouping

20xy -4y +35x -7

4y(5x-1) +7(5x-1)

then factor out 5x-1

(5x-1)(4y+7)
