expand (x+3)(x^2-2x+5)

expand

(x + 3) (x^{2} - 2 x + 5)

x^{3} + x^{2} - x + 15

Solution steps

(x + 3) (x^{2} - 2 x + 5)

Distribute parentheses

= x x^{2} + x (- 2 x) + x \cdot 5 + 3 x^{2} + 3 (- 2 x) + 3 \cdot 5

Simplify

x x^{2} + x (- 2 x) + x \cdot 5 + 3 x^{2} + 3 (- 2 x) + 3 \cdot 5 : x^{3} + x^{2} - x + 15

= x^{3} + x^{2} - x + 15

(- 2 + 2 i) - (- 7 + 7 i)

(- 3 - 7 i) + (- 12 + 6 i)

3 x^{3} y^{2} + 3 y^{2}

427 - 75
