expand (x^2-5x+6)(x^2-1)

expand

(x^{2} - 5 x + 6) (x^{2} - 1)

x^{4} - 5 x^{3} + 5 x^{2} + 5 x - 6

Solution steps

(x^{2} - 5 x + 6) (x^{2} - 1)

Distribute parentheses

= x^{2} x^{2} + x^{2} (- 1) - 5 x x^{2} - 5 x (- 1) + 6 x^{2} + 6 (- 1)

Simplify

x^{2} x^{2} + x^{2} (- 1) - 5 x x^{2} - 5 x (- 1) + 6 x^{2} + 6 (- 1) : x^{4} - 5 x^{3} + 5 x^{2} + 5 x - 6

= x^{4} - 5 x^{3} + 5 x^{2} + 5 x - 6

(8 s^{- 3} t^{- 4})^{2}

121 x^{2} - 64

\frac{( + 30 )}{( - 5 )}

\frac{48}{6}

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