Question

factorise 7m ( 4-x)(x-4)​

Answer 1

Answer:

Step-by-step explanation:

Step 1: 7m(4 - x)( x - 4)

           7m(-x + 4)( x - 4)

Step2: 7m(-x + 4)( x - 4)

          -7mx(x - 4) + 28m(x - 4)

Step 3: -7mx(x - 4) + 28m(x - 4)

Step 4: -7mx² + 28mx + 28m(x - 4)

            -7mx² + 28mx +28mx - 112m

Step 5: -7mx² + 28mx + 28mx - 112m

            -7mx² + 56mx - 112m

Solution: -7mx² + 56mx - 112m
