expand (5x-7y=79)(x+y)

expand

(5 x - 7 y = 79) (x + y)

5 x^{2} + 5 x y - 7 y = 79 y

Solution steps

(5 x - 7 y = 79) (x + y)

= (5 x - 7 \cdot 79 = y) (x + y)

Apply FOIL method:

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

a = 5 x, b = - 7 y = 79, c = x, d = y

= 5 xx + 5 x y + (- 7 y = 79) x + (- 7 y = 79) y

Apply minus-plus rules

+ (- a) = - a

5 xx + 5 x y - 7 y = 79 x - 7 y = 79 y

Expand

5 xx + 5 x y - 7 y : 5 x^{2} + 5 x y - 7 y

5 x^{2} + 5 x y - 7 y = 79 y

4 (e - \frac{1}{e}) + 2 e^{2} - \frac{2}{e ^{2}}

\frac{1}{x ^{\frac{1}{3}} ( 1 - x )}

x^{2} (\frac{12}{x} - \frac{x}{4})

(n - 56)^{4} (6 - \frac{n - 7}{8})

\frac{x ( x + 5 )}{x ^{2} + 2 x + 20}
