expand (x-2y=6,)(3x+2y=2)

expand

(x - 2 y = 6,) (3 x + 2 y = 2)

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

Solution steps

(x - 2 y = 6,) (3 x + 2 y = 2)

= (x - 2 \cdot 6 =, y) (3 x + 2 \cdot 2 = y)

Apply FOIL method:

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

a = x, b = - 2 y = 6,, c = 3 x, d = 2 y = 2

x \cdot 3 x + x \cdot 2 y = 2 + (- 2 y = 6,) \cdot 3 x + (- 2 y = 6,) \cdot 2 y = 2

Apply minus-plus rules

+ (- a) = - a

3 xx + 2 x y = 2 - 2 y = 6, 3 x - 2 y = 6, 2 y = 2

Expand

3 xx + 2 x y : 3 x^{2} + 2 x y

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

ln (2) (2^{x} + x \cdot 2^{x} \cdot ln (2))

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

\frac{9 x - 27}{( x - 5 ) ( x + 4 )}

\frac{4 ( s + 6.25 )}{s ( s + 3.63 ) ( s + 28.6 )}

(3 x^{2} + 5) d y + (6 x y) d y
