8x3 + 4x2 + 6x + 3 = 4x2(2x + 1) + 3(2x + 1) = (2x + 1)(4x2 + 3)
4x3+10x2-6x 2x(2x2+5x-3) 2x(2x-1)(x+3)
(2x-4)(x-1) = 0

8x3 + 4x2 + 6x + 3 = 4x2(2x + 1) + 3(2x + 1) = (2x + 1)(4x2 + 3)
4x3+10x2-6x 2x(2x2+5x-3) 2x(2x-1)(x+3)
The GCF is 2x.
6x2 + 10x = 2x*(3x + 5)
(2x-4)(x-1) = 0
8x2 + 6x - 9 = 8x2 + 12x - 6x - 9 = 4x(2x + 3) - 3(2x + 3) = (2x + 3)(4x - 3)
3x(2x + 1)
(2x - 1)(6x + 5)

Oh, dude, when you add 6x squared and 2x squared, you get 8x squared. It's like combining 6 apples with 2 apples and ending up with 8 apples. So, in math terms, 6x squared plus 2x squared equals 8x squared. Easy peasy!
12+2x = 6x-18 12+18 = 6x-2x 30 = 4x Divide both sides of the equation by 4 to find the value of x: x = 7.5
