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

simplify

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

3 x^{2}

Solution steps

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

Simplify

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

= x^{2} - y^{2} - (x + y) (x - y) + 3 x^{2}

Group like terms

= x^{2} + 3 x^{2} - y^{2} - (x + y) (x - y)

Add similar elements:

x^{2} + 3 x^{2} = 4 x^{2}

= 4 x^{2} - y^{2} - (x + y) (x - y)

Expand

- (x + y) (x - y) : - x^{2} + y^{2}

= 4 x^{2} - y^{2} - x^{2} + y^{2}

Group like terms

= 4 x^{2} - x^{2} - y^{2} + y^{2}

Add similar elements:

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

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

Add similar elements:

- y^{2} + y^{2} = 0

= 3 x^{2}

x^{2} + x - 6 < 0

x y^{2} + x - y^{2} z - z

- 10 \leq - 7 + u

10 + 2 (9 - 5) - 16 \div 8

x^{6} - 256 x^{2}
