iv. (7p + 6q )(7p + 6q )
please do process also in copy

Answer 1

Answer:

4a²+ 6ab+5bc

4x+5y 4x-5y

Answer 2

Step-by-step explanation:

1) 4a²×6ab×5bc =120a³b²c

2)7a(4a+5c-9e) =28a²+35ac-63ae

3)(4x+5y)(4x-5y) =(4x)²-(5y)²= 16x²-25y²

4) (7p+6q)(7p+6q)=(7p+6q)²=(7p)²-2×7p×6q+(6q)²=49p²-84pq+36q²
