Maharashtra Board Solution
Divide and write the quotient and the remainder. i. 21m² ÷ 7m ii. 40a³ ÷ (-10a) iii. (- 48p4) ÷ (- 9p2) iv. 40m5 ÷ 30m3 v. (5x3 – 3x2) ÷ x² vi. (8p3 – 4p2) ÷ 2p2 vii. (2y3 + 4y2 + 3 ) ÷ 2y2 viii. (21x4 – 14x2 + 7x) ÷ 7x3 ix. (6x5 – 4x4 + 8x3 + 2x2) ÷ 2x2 x. (25m4 – 15m3 + 10m + 8) ÷ 5m3
Solution & Step-by-Step Answer:
i. 21m² ÷ 7m ∴ Quotient = 3m Remainder = 0
ii. 40a³ ÷ (-10a)
∴ Quotient = -4a²
Remainder = 0
iii. (- 48p4) ÷ (- 9p2)
∴ Quotient = p²
Remainder = 0
iv. 40m5÷ 30m3
∴ Quotient = m²
Remainder = 0
v. (5x3– 3x2) ÷ x²
∴ Quotient = 5x – 3
Remainder = 0
vi. (8p3– 4p2) ÷ 2p2
∴ Quotient = 4p – 2
Remainder = 0
vii. (2y3+ 4y2+ 3 ) ÷ 2y2
∴ Quotient = y + 2
Remainder = 3
viii. (21x4– 14x2+ 7x) ÷ 7x3
∴ Quotient = 3x
Remainder = -14x² + 7x
ix. (6x5– 4x4+ 8x3+ 2x2) ÷ 2x2
∴ Quotient = 3x³ – 2x² + 4x + 1
Remainder = 0
x. (25m4– 15m3+ 10m + 8) ÷ 5m3
∴ Quotient = 5m – 3
Remainder = 10m + 8
