Simplify (X^5) (X^2) ?

Answer: x 2 - 3x - 10

Explanation:

each term in the second factor is multiplied by each term

in the first factor

⇒ (x - 5) (x + 2)

= x (x + 2) - 5 (x + 2) ← distribute

= (x * x) + (x * 2) + ( - 5 * x) + ( - 5 * 2)

= x 2 + 2 x - 5 x - 10 ← collect like terms

= x 2 - 3x - 10

just sum the power

5 + 2 = 7

x^7
