expand sqrt(2)(x^2+y^2-6y+9)

expand

2 (x^{2} + y^{2} - 6 y + 9)

2 x^{2} + 2 y^{2} - 62 y + 92

Solution steps

2 (x^{2} + y^{2} - 6 y + 9)

Distribute parentheses

= 2 x^{2} + 2 y^{2} + 2 (- 6 y) + 2 \cdot 9

Simplify

2 x^{2} + 2 y^{2} + 2 (- 6 y) + 2 \cdot 9 : 2 x^{2} + 2 y^{2} - 62 y + 92

= 2 x^{2} + 2 y^{2} - 62 y + 92

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

(a + b x) (cos (5 x) + sin (5 x))

e^{x s i n (x)} + e^{x s i n (x)} x (sin (x) + x cos (x))

(- x + 2 - 3) (x + 2 - 3)

(4 x^{2} + 5 y^{2}) i + 3 x y j
