simplify (xsqrt(2)+y)(xsqrt(2)-y)

simplify

(x 2 + y) (x 2 - y)

2 x^{2} - y^{2}

Solution steps

(x 2 + y) (x 2 - y)

Apply Difference of Two Squares

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

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

(1 - \frac{1}{e ^{\frac{1}{5}}})^{2}

(x cos (x)) (cos (x) - x sin (x))

\frac{1}{x ^{3}} (\frac{d y}{d x} - \frac{3}{x} y = x^{4})

(x + 2 i)^{4}

10 (x + Δ x)^{2}
