expand (x^2-3x+1)(x^2-1)

expand

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

x^{4} - 3 x^{3} + 3 x - 1

Solution steps

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

Distribute parentheses

= x^{2} x^{2} + x^{2} (- 1) - 3 x x^{2} - 3 x (- 1) + 1 \cdot x^{2} + 1 \cdot (- 1)

Simplify

x^{2} x^{2} + x^{2} (- 1) - 3 x x^{2} - 3 x (- 1) + 1 \cdot x^{2} + 1 \cdot (- 1) : x^{4} - 3 x^{3} + 3 x - 1

= x^{4} - 3 x^{3} + 3 x - 1

49 p m^{2} - 7 p m^{4}

∣ 4 - 3 ∣

- 4 x + 1 - 7 x^{2} + 4 x + 2

600 - 0.1 \cdot 2000

\frac{- 64}{( - 8 )}
