expand (x^2y-2xy+1)+(-3x^2y+1/2)

expand

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

- 2 x^{2} y - 2 x y + \frac{3}{2}

Solution steps

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

Remove parentheses:

(a) = a

= x^{2} y - 2 x y + 1 - 3 x^{2} y + \frac{1}{2}

Group like terms

= x^{2} y - 3 x^{2} y - 2 x y + \frac{1}{2} + 1

Add similar elements:

x^{2} y - 3 x^{2} y = - 2 x^{2} y

= - 2 x^{2} y - 2 x y + \frac{1}{2} + 1

Combine the fractions

1 + \frac{1}{2} : \frac{3}{2}

= - 2 x^{2} y - 2 x y + \frac{3}{2}

1 + 500 (1 - (1 - \frac{1}{1000})^{500})

\frac{( 4 x )}{( ( x - a ) ^{(2)} )}

\frac{2 ( x - 3 ) ( 3 x - 4 )}{( x ^{2} - 4 ) ^{2}}

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