Question

multiply x^4(x^3-5)
and (x^2-2)(x^4-3)

Answer 1

$x^4(x^3-5)$

${x}^{4}{x}^{3}+{x}^{4}\times (-5)$

${x}^{4+3}+{x}^{4}\times (- 5)$

${x}^{7}+{x}^{4}\times( -5)$

${x}^{7}-5{x}^{4}$

Answer 2

Answer:

☆ x⁴ (x³ - 5) = x⁷ - 5x⁴.

☆ (x² - 2)(x⁴ - 3) = x⁶ - 2x⁴ - 3x² + 6.

Step-by-step explanation:

• x⁴ (x³ - 5).

x⁷ - 5x⁴.

• (x² - 2)(x⁴ - 3).

x² (x⁴ - 3) -2 (x⁴ - 3).

x⁶ - 3x² - 2x⁴ + 6.

x⁶ - 2x⁴ - 3x² + 6.
