Question

Find the product of following algebraic expressions [8]
i.4a²,6ab and 5bc
ii.7a (4a + 5c - 9e)
iii. (4x + 5y) (4x -5y)
iv.(7p + 6q )(7p + 6q )
please do the process also
full process friends i need our help

Answer 1

Answer:

i) 120a³b²c

ii) 28a²+35ac-63ae

iii) 16x²-25y²

iv) 49p²+36q²+84pq

Steps:

i. (4a²)(6ab)(5bc)

(4×6×5)(a²abbc)

=(120a³b²c)

ii. 7a(4a)+7a(5c)+7a(-9e)

28a²+35ac-63ae

iii. 4x(4x-5y)+5y(4x-5y)

16x²-20xy+20xy-25y²

16x²-25y²

iv. 7p(7p+6q)+6q(7p+6q)

49p²+42pq+42pq+36q²

49p²+84pq+36q²
