expand-4y(5sqrt(2)+2sqrt(7))

expand

- 4 y (52 + 27)

- 202 y - 87 y

Solution steps

- 4 y (52 + 27)

= - 4 (52 + 27) y

Apply the distributive law:

a (b + c) = ab + a c

a = - 4 y, b = 52, c = 27

= - 4 y \cdot 52 + (- 4 y) \cdot 27

Apply minus-plus rules

+ (- a) = - a

= - 4 \cdot 52 y - 4 \cdot 27 y

Simplify

- 4 \cdot 52 y - 4 \cdot 27 y : - 202 y - 87 y

= - 202 y - 87 y

4 + c

\frac{8 x ( x - 2 ) - 5}{x ( x - 2 ) + 1}

(x + 2) (x + 4)^{'}

5 + (3 \cdot 4) + [3 + (5 - 2)]

π (- x^{2} - 4 x)^{2}
