expand (4x+y=10,)(2x+y=4)

expand

(4 x + y = 10,) (2 x + y = 4)

8 x^{2} + 4 x y = 4

Solution steps

(4 x + y = 10,) (2 x + y = 4)

= (4 x + 10 =, y) (2 x + 4 = y)

Apply FOIL method:

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

a = 4 x, b = y = 10,, c = 2 x, d = y = 4

4 x \cdot 2 x + 4 x y = 4 + y = 10, 2 x + y = 10, y = 4

4 \cdot 2 xx + 4 x y = 4 + y = 10, 2 x + y = 10, y = 4

Expand

4 \cdot 2 xx + 4 x y : 8 x^{2} + 4 x y

8 x^{2} + 4 x y = 4

(a + b) (c d e)

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

\frac{( t + 2 ) ^{3}}{( x ^{2} + t ^{2} + 3 t - x t + 3 ) ^{2}}

(t + 3)^{2} \cdot e^{5 t}

\frac{x ^{2} - 2 x - 3}{( x ^{2} - x + 4 ) ^{2}}
