expand (5x+8y=11,5)(3x+5y=70)

expand

(5 x + 8 y = 11, 5) (3 x + 5 y = 70)

15 x^{2} + 25 x y = 70

Solution steps

(5 x + 8 y = 11, 5) (3 x + 5 y = 70)

= (5 x + 8 \cdot 11 \cdot 5 =, y) (3 x + 5 \cdot 70 = y)

Apply FOIL method:

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

a = 5 x, b = 8 y = 11, 5, c = 3 x, d = 5 y = 70

5 x \cdot 3 x + 5 x \cdot 5 y = 70 + 8 y = 11, 5 \cdot 3 x + 8 y = 11, 5 \cdot 5 y = 70

5 \cdot 3 xx + 5 \cdot 5 x y = 70 + 8 y = 11, 5 \cdot 3 x + 8 y = 11, 5 \cdot 5 y = 70

Expand

5 \cdot 3 xx + 5 \cdot 5 x y : 15 x^{2} + 25 x y

15 x^{2} + 25 x y = 70

\frac{s + 2}{( s + 1 ) ( s ^{2} + 4 )}

4 x^{2} \cdot (\frac{15}{x} - \frac{2 x}{5})

\frac{( 8 )}{( s + 4 ) ( s ^{2} + 2 s + 2 )}

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

\frac{( s - 2 ) ( 3 s + 1 ) ^{2}}{9}
