1. 8x^5 + 10x^4 = 4x^3 + 5x^ 2

2. a ^ 4 + 2a^3 + a ^ 2 = 0

Solve :
1.
8x^5 + 10x^4 = 3x^3 + 5x^ 2
8x^5 +10x^4 -3x^3 -5x^2 = 0,
x^2(8x^3 +10x^2 -3x -5) = 0,
x^2(x+1)(8x^2 +2x -5) = 0,

x^2(x+1)(8x-7.4)(x+5.4) = 0,
Hence,
x = 0, x = -1, x = 7.4/8, and x = -5.4 >====================< ANSWER

2.
a ^ 4 + 2a^3 + a ^ 2 = 0,
a^2(a^2 +2a +1) = 0,
a^2(a+1)^2 = 0,
Hence,
x = 0, x = -1 >=========================< ANSWER

1. x^2(8X^3+10X^2-4X-5X)
2. (a^2(a^2+2a+1))
