Factor 5a^2-30a+45, and 2x^5+x^4-2x-1.

Mrrafil [7]

Step-by-step explanation:

${5a}^{2} - 30a + 45$

$5( {a}^{2} - 6a + 9)$

5(a-3)(a-3)

5(a-3)^2

${2x}^{5} + {x}^{4} - 2x - 1$

X^4(2x+1) - (2x+1)

(x^4-1)(2x+1)

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

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

Vlada [557]

Answer:

Cole spend 47.587 on buying gifts for each person.
