simplify 3x(x^n+2-y)+y(3x-4y)-3x^n+3

simplify

3 x (x^{n} + 2 - y) + y (3 x - 4 y) - 3 x^{n} + 3

3 x^{1 + n} + 6 x - 4 y^{2} - 3 x^{n} + 3

Solution steps

3 x (x^{n} + 2 - y) + y (3 x - 4 y) - 3 x^{n} + 3

Expand

3 x (x^{n} + 2 - y) : 3 x^{1 + n} + 6 x - 3 x y

= 3 x^{1 + n} + 6 x - 3 x y + y (3 x - 4 y) - 3 x^{n} + 3

Expand

y (3 x - 4 y) : 3 x y - 4 y^{2}

= 3 x^{1 + n} + 6 x - 3 x y + 3 x y - 4 y^{2} - 3 x^{n} + 3

Add similar elements:

- 3 x y + 3 x y = 0

= 3 x^{1 + n} + 6 x - 4 y^{2} - 3 x^{n} + 3

\frac{k \cdot ( \frac{27}{2} )}{( \frac{9}{4} ) i}

a^{2} \frac{b ^{3}}{2}

(0.75 x)^{2}

\frac{2}{( a ^{2} + a )} + \frac{( a - 2 )}{a}

(\frac{x + 1}{( 2 x )})^{7} \cdot (\frac{2 x - 1}{x})^{5}
