expand (7x+10=1,4)(x-2y=10)

expand

(7 x + 10 = 1, 4) (x - 2 y = 10)

7 x^{2} - 14 x y = 10

Solution steps

(7 x + 10 = 1, 4) (x - 2 y = 10)

= (7 x + 10 \cdot 1 \cdot 4 =,) (x - 2 \cdot 10 = y)

Apply FOIL method:

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

a = 7 x, b = 10 = 1, 4, c = x, d = - 2 y = 10

7 xx + 7 x (- 2 y = 10) + 10 = 1, 4 x + 10 = 1, 4 (- 2 y = 10)

Apply minus-plus rules

+ (- a) = - a

7 xx - 7 \cdot 2 x y = 10 + 10 = 1, 4 x - 10 = 1, 4 \cdot 2 y = 10

Expand

7 xx - 7 \cdot 2 x y : 7 x^{2} - 14 x y

7 x^{2} - 14 x y = 10

2 (π x^{4} - π x)

(- d + 2 (\frac{84}{d}) - 2 = 0) d

y (1 + ln (x y) + 2 x) d x + (x - 2 y^{2}) d y

lo g_{(x + 1) (x + 2)} (x)

\frac{5}{s ( s + 2 ) ( 0.5 s + 1 )}
