expand (5x+5y+5z=60,)(-4x-5y+3z=17)

expand

(5 x + 5 y + 5 z = 60,) (- 4 x - 5 y + 3 z = 17)

- 20 x^{2} - 25 x y + 15 x z = 17

Solution steps

(5 x + 5 y + 5 z = 60,) (- 4 x - 5 y + 3 z = 17)

= (5 x + 5 y + 5 \cdot 60 =, z) (- 4 x - 5 y + 3 \cdot 17 = z)

Distribute parentheses

5 x (- 4 x) + 5 x (- 5 y) + 5 x \cdot 3 z = 17 + 5 y (- 4 x) + 5 y (- 5 y) + 5 y \cdot 3 z = 17 + 5 z = 60, (- 4 x) + 5 z = 60, (- 5 y) + 5 z = 60, 3 z = 17

Apply minus-plus rules

+ (- a) = - a

- 5 \cdot 4 xx - 5 \cdot 5 x y + 5 \cdot 3 x z = 17 - 5 \cdot 4 x y - 5 \cdot 5 yy + 5 \cdot 3 yz = 17 - 5 z = 60, 4 x - 5 z = 60, 5 y + 5 z = 60, 3 z = 17

Expand

- 5 \cdot 4 xx - 5 \cdot 5 x y + 5 \cdot 3 x z : - 20 x^{2} - 25 x y + 15 x z

- 20 x^{2} - 25 x y + 15 x z = 17

\frac{( E - E - V ) ^{4}}{V ^{2}}

\frac{( 2 y - y ^{2} ) ^{2}}{2}

A (x + 2, 4) B (2, y - 4)

\frac{90 2}{2}

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