Answer 1

Answer:

9a(6a-5b) -12a²(6a-5b)

(9a- 12a²) (6a-5b).

taking 6a-5b as a common.

=3a(3-4a)(6a-5b).

taking 3a as a common factor if the quadratic 9a-12a²

--------------------------------------------------------------------------------------------------------------

9a(6a-5b)-12a2(6a-5b)

Final result :

-3a • (6a - 5b) • (4a - 3)

Step by step solution :

Step 1 :

Equation at the end of step 1 :

(9a • (6a - 5b)) - ((22•3a2) • (6a - 5b))

Step 2 :

Equation at the end of step 2 :

(9a • (6a - 5b)) - (22•3a2) • (6a - 5b)

Step 3 :

Equation at the end of step 3 :

9a • (6a - 5b) - (22•3a2) • (6a - 5b)

Step 4 :

Pulling out like terms :

4.1 Pull out 6a-5b

After pulling out, we are left with :

(6a-5b) • ( 9a * 1 +( 22 • 3a2 * (-1) ))

Step 5 :

Pulling out like terms :

5.1 Pull out like factors :

9a - 12a2 = -3a • (4a - 3)
