expand (a-1)x^2+(2-3a)x+20

expand

(a - 1) x^{2} + (2 - 3 a) x + 20

a x^{2} - x^{2} + 2 x - 3 a x + 20

Solution steps

(a - 1) x^{2} + (2 - 3 a) x + 20

= x^{2} (a - 1) + x (2 - 3 a) + 20

Expand

x^{2} (a - 1) : a x^{2} - x^{2}

= a x^{2} - x^{2} + x (2 - 3 a) + 20

Expand

x (2 - 3 a) : 2 x - 3 a x

= a x^{2} - x^{2} + 2 x - 3 a x + 20

(2 a \cdot 3)^{2}

[\frac{x ^{4}}{4} - x^{3} - \frac{x ^{2}}{2} + 3 x]_{0}^{1}

(d^{- 5})^{- 2}

lo g_{10} (x) (x - 2)

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