expand (y=3,x-1)(y=2x-4)

expand

(y = 3, x - 1) (y = 2 x - 4)

y = 2 x + 4

Solution steps

(y = 3, x - 1) (y = 2 x - 4)

= (3 =, y x - 1) (2 = y x - 4)

Apply FOIL method:

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

a = y = 3, x, b = - 1, c = y = 2 x, d = - 4

y = 3, x y = 2 x + y = 3, x (- 4) + (- 1) y = 2 x + (- 1) (- 4)

Apply minus-plus rules

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

y = 3, y x = 2 x - y = 3, 4 x - 1 \cdot y = 2 x + 1 \cdot 4

Expand

2 x + 1 \cdot 4 : 2 x + 4

y = 2 x + 4

\frac{8 - 10 x}{5}

\frac{2 ( 3 + a )}{b}

2 π (y + 5) (1 - y)

(- 1000 e^{- 10000 x} + 2400 e^{- 40000 x}) \cdot 0.02

(3 + 1)^{k}
