expand (x-0.5y+1=0,)(2x-y+6=0)

expand

(x - 0.5 y + 1 = 0,) (2 x - y + 6 = 0)

2 x^{2} - x y + 6 x = 0

Solution steps

(x - 0.5 y + 1 = 0,) (2 x - y + 6 = 0)

= (x - 0.5 y + 1 \cdot 0 =,) (2 x - y + 6 \cdot 0 =)

Distribute parentheses

x \cdot 2 x + x (- y) + x \cdot 6 = 0 + (- 0.5 y) \cdot 2 x + (- 0.5 y) (- y) + (- 0.5 y) \cdot 6 = 0 + 1 = 0, 2 x + 1 = 0, (- y) + 1 = 0, 6 = 0

Apply minus-plus rules

+ (- a) = - a, (- a) (- b) = ab

2 xx - x y + 6 x = 0 - 2 \cdot 0.5 x y + 0.5 yy - 6 \cdot 0.5 y = 0 + 1 = 0, 2 x - 1 = 0, y + 1 = 0, 6 = 0

Expand

2 xx - x y + 6 x : 2 x^{2} - x y + 6 x

2 x^{2} - x y + 6 x = 0

ln (x) (x^{2} - 1)

(2 + 3 x - 4 x^{2})^{5}

- 8 d + (- 1) + 9 d^{2} + 8 d

\frac{2 x}{x}

2 (d + f^{2} - e^{2})^{2}
