expand (1.2)(3x-4y-20=0)

expand

(1.2) (3 x - 4 y - 20 = 0)

3.6 x - 4.8 y - 24 = 0

Solution steps

(1.2) (3 x - 4 y - 20 = 0)

= (1.2) (3 x - 4 y - 20 \cdot 0 =)

Distribute parentheses

= (1.2) \cdot 3 x + (1.2) (- 4 y) + (1.2) (- 20 = 0)

Apply minus-plus rules

+ (- a) = - a

3 (1.2) x - 4 (1.2) y - 20 (1.2) = 0

Expand

3 (1.2) x - 4 (1.2) y - 20 (1.2) : 3.6 x - 4.8 y - 24

3.6 x - 4.8 y - 24 = 0

2 (n (n + 1) (2 n + 1))

3 (2 - x + 6 = 0)

\frac{( 5 x - 1 ) ( 5 x - 6 )}{5}

\frac{x + 3}{( x + 1 ) ( x ^{2} + 4 )}

(x, y) \Rightarrow (x + 10, y + 8)
