expand (7x+8y=29,0)(5x+11y=2600)

expand

(7 x + 8 y = 29, 0) (5 x + 11 y = 2600)

35 x^{2} + 77 x y = 2600

Solution steps

(7 x + 8 y = 29, 0) (5 x + 11 y = 2600)

= (7 x + 8 \cdot 29 \cdot 0 =, y) (5 x + 11 \cdot 2600 = y)

Apply FOIL method:

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

a = 7 x, b = 8 y = 29, 0, c = 5 x, d = 11 y = 2600

7 x \cdot 5 x + 7 x \cdot 11 y = 2600 + 8 y = 29, 0 \cdot 5 x + 8 y = 29, 0 \cdot 11 y = 2600

7 \cdot 5 xx + 7 \cdot 11 x y = 2600 + 8 y = 29, 0 \cdot 5 x + 8 y = 29, 0 \cdot 11 y = 2600

Expand

7 \cdot 5 xx + 7 \cdot 11 x y : 35 x^{2} + 77 x y

35 x^{2} + 77 x y = 2600

\frac{( 1 + x ) ^{2}}{100}

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

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

- x (cos (ln (x)) - sin (ln (x)))

(2 x + x^{(2)} e^{(x)})^{(2)}
