expand (x+2)(x-2)(x+17/10)(x-17/10)

expand

(x + 2) (x - 2) (x + \frac{17}{10}) (x - \frac{17}{10})

x^{4} - \frac{689 x ^{2}}{100} + \frac{289}{25}

Solution steps

(x + 2) (x - 2) (x + \frac{17}{10}) (x - \frac{17}{10})

Expand

(x + 2) (x - 2) (x + \frac{17}{10}) (x - \frac{17}{10}) : (x^{2} - 4) (x + \frac{17}{10}) (x - \frac{17}{10})

= (x^{2} - 4) (x + \frac{17}{10}) (x - \frac{17}{10})

Apply Difference of Two Squares

(x + \frac{17}{10}) (x - \frac{17}{10}) : x^{2} - \frac{289}{100}

= (x^{2} - 4) (x^{2} - \frac{289}{100})

Apply FOIL method

(x^{2} - 4) (x^{2} - \frac{289}{100}) : x^{4} - \frac{689 x ^{2}}{100} + \frac{289}{25}

= x^{4} - \frac{689 x ^{2}}{100} + \frac{289}{25}

x 2 - 1.695 x + 0.2583

(9 + 3) (7 + 2)

\frac{( 3 - w ) ^{2}}{2}

(y_{5})^{2}

\frac{( ( n - 1 ) \cdot ( n ^{3} - n ^{2} - 14 \cdot n + 12 ) )}{12}
