expand (-x+2y=4,)(2x-4y=3)

expand

(- x + 2 y = 4,) (2 x - 4 y = 3)

- 2 x^{2} + 4 x y = 3

Solution steps

(- x + 2 y = 4,) (2 x - 4 y = 3)

= (- x + 2 \cdot 4 =, y) (2 x - 4 \cdot 3 = y)

Apply FOIL method:

(a + b) (c + d) = a c + a d + b c + b d

a = - x, b = 2 y = 4,, c = 2 x, d = - 4 y = 3

(- x) \cdot 2 x + (- x) (- 4 y = 3) + 2 y = 4, 2 x + 2 y = 4, (- 4 y = 3)

Apply minus-plus rules

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

- 2 xx + 4 x y = 3 + 2 y = 4, 2 x - 2 y = 4, 4 y = 3

Expand

- 2 xx + 4 x y : - 2 x^{2} + 4 x y

- 2 x^{2} + 4 x y = 3

4.8 (x - \frac{1}{75 = - 9.6})

e^{r t} (r^{3} - 3 r^{2} + 2 r)

\frac{x + 1}{( x + 2 ) ( x - 1 )}

(a + b + c + d + e + f + g + h + i)^{2}

(\frac{40 - x}{2})^{2}
