simplify (5sqrt(y)+sqrt(x))(5sqrt(y)-3sqrt(x))

simplify

(5 y + x) (5 y - 3 x)

25 y - 10 y x - 3 x

Solution steps

(5 y + x) (5 y - 3 x)

Expand

(5 y + x) (5 y - 3 x) : 25 y - 15 y x + 5 x y - 3 x

= 25 y - 15 y x + 5 x y - 3 x

Add similar elements:

- 15 y x + 5 y x = - 10 y x

= 25 y - 10 y x - 3 x

\frac{3 ( 1 - sin ( x ) )}{2 cos ( x )}

\frac{2 x ^{3}}{( 1 - x ^{2} ) ^{2}}

3 (x - 3)

\frac{6 x + 13}{( x + 3 ) ( x + 2 )}

(i + k + j + 2) \times (i + ik + kj + j)^{2}
