Step 1.1

Factor ${(2 a - 3 b)}^{2} {(5 a - 7 b)}^{2}$ out of ${(2 a - 3 b)}^{2} {(5 a - 7 b)}^{3}$ .

${(2 a - 3 b)}^{2} {(5 a - 7 b)}^{2} (5 a - 7 b) - {(2 a - 3 b)}^{3} {(5 a - 7 b)}^{2}$

Step 1.2

Factor ${(2 a - 3 b)}^{2} {(5 a - 7 b)}^{2}$ out of $- {(2 a - 3 b)}^{3} {(5 a - 7 b)}^{2}$ .

${(2 a - 3 b)}^{2} {(5 a - 7 b)}^{2} (5 a - 7 b) + {(2 a - 3 b)}^{2} {(5 a - 7 b)}^{2} (- (2 a - 3 b))$

Step 1.3

Factor ${(2 a - 3 b)}^{2} {(5 a - 7 b)}^{2}$ out of ${(2 a - 3 b)}^{2} {(5 a - 7 b)}^{2} (5 a - 7 b) + {(2 a - 3 b)}^{2} {(5 a - 7 b)}^{2} (- (2 a - 3 b))$ .

${(2 a - 3 b)}^{2} {(5 a - 7 b)}^{2} (5 a - 7 b - (2 a - 3 b))$

Step 2

Apply the distributive property.

${(2 a - 3 b)}^{2} {(5 a - 7 b)}^{2} (5 a - 7 b - (2 a) - (- 3 b))$

Step 3

Multiply $2$ by $- 1$ .

${(2 a - 3 b)}^{2} {(5 a - 7 b)}^{2} (5 a - 7 b - 2 a - (- 3 b))$

Step 4

Multiply $- 3$ by $- 1$ .

${(2 a - 3 b)}^{2} {(5 a - 7 b)}^{2} (5 a - 7 b - 2 a + 3 b)$

Step 5

Subtract $2 a$ from $5 a$ .

${(2 a - 3 b)}^{2} {(5 a - 7 b)}^{2} (3 a - 7 b + 3 b)$

Step 6

Add $- 7 b$ and $3 b$ .

${(2 a - 3 b)}^{2} {(5 a - 7 b)}^{2} (3 a - 4 b)$
