Question

a(x-y)-b(Y-x) factorise this
​

Answer 1

Step-by-step explanation:

a(x-y)+b(y-x)

Final result :

(x - y) • (b - a)

Step by step solution :

Step 1 :

Equation at the end of step 1 :

(a • (x - y)) + b • (y - x)

Step 2 :

Equation at the end of step 2 :

a • (x - y) + b • (y - x)

Step 3 :

Pulling out like terms :

3.1 Pull out x-y

Note that y-x =(-1)• x-y

After pulling out, we are left with :

(x-y) • ( a * (-1) - b * (-1) ))

Final result :

(x - y) • (b - a)

Answer 2

Answer:

ax-ay-by+bx

ax+bx-ay-by

x(a-b) +y(a-b) sign will change here

(a-b) (x-y)
