Find the product of:

(i) 2x, 5y and 7z                  (ii) 4xy, 5x²y² and 6x³y³

62.

 Multiply:

(i) (–3x) and (–5y + 2) (ii) 5xy and (y² + 3)

Simplify the expressions and evaluate them as directed:

(i) x(x – 3) + 2 for x = 1 (ii) 3y(2y – 7) – 3(y – 4) – 63 for y = –2.

Multiply (x – 2) and (2x + 3).

Simplify (a + b) (a - 2b + 3c) - (2a - 3b)c

Multiply the binomials

(2x + 5) and (4x - 3)

Multiply the binomials

(y - 8)  and  (3y - 4)

Multiply the binomials

(2.5l - 0. 5m) and (2.5l + 0.5m)

Multiply the binomials

(a + 3b) and (x + 5)

(2pq + 3q²)   and (3pq - 2q² )
