Question

solve:

a^5 + 6a^4 + 5a = 0

Answer 1

a= -1, a = 0

Answer 2

a^5 + 6a^4 + 5a^3 = 0 First, factor out the a^3 term
a^3 * (a^2 + 6a + 5) = 0 Next, we need factors of 5 that add up to 6, easy because 5 is prime...
a^3 * (a + 1)(a + 5) = 0 Your values that make this true are a=0, a=-1, a=-5
