1. x(x+3) = x²+3x
Step by Step:
Apply the Distributive law: (a=x, b=x, c=3)
= xx + x × 3
= xx + 3x
= xx = x²
= x²+3x
-----------------------------------------------------------
2. 3x(4x-7) = 12x²-21x
Step by Step:
Apply the Distributive law: a(b-c) = ab - ac
(a=3x, b=4x, c=7)
= 3x × 4x - 3x × 7
= 3 × 4xx - 3 × 7x
= 12x² - 21x
-----------------------------------------------------------
3. -5x(6x-2) = -30x²+10x
Step by Step:
Apply the Distributive law: a(b-c) = ab - ac
(a = -5x, b = 6x, c = 2)
= -5x × 6x - (-5x) × 2
Apply minus - plus rule: -(-a) = a
= -5x × 6xx + 5 × 2x
= -30x² + 10x
-----------------------------------------------------------
1. x(x+3) = x²+3x
2. 3x(4x-7) = 12x²-21x
3. -5x(6x-2) = -30x² + 10x
