expand (3,-3)y(-1,21)

expand

(3, - 3) y (- 1, 21)

3 (- 1 \cdot 21,) y, - 3 (- 1 \cdot 21,) y

Solution steps

(3, - 3) y (- 1, 21)

= (3, - 3) (- 1 \cdot 21,) y

Apply the distributive law:

a (b - c) = ab - a c

a = y (- 1, 21), b = 3,, c = 3

= y (- 1, 21) \cdot 3, - y (- 1, 21) \cdot 3

= 3 (- 1 \cdot 21,) y, - 3 (- 1 \cdot 21,) y

π (2 x - 4)^{2}

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

(x - 5)^{2}

(w - y)^{2}

(4 - t)^{2}
