X(x+3)=?<br>3x(4x-7)=?<br>-5x(6x-2)​
Anestetic [448]

-----------------------------------------------------------

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
