10x - 25 = 4x + 510x - 4x = 25 + 56x = 30x = 5
5
16x2 + 40x + 25 = 16x2 + 20x + 20x + 25 = 4x(4x + 5) + 5(4x + 5) = (4x + 5)(4x + 5) = (4x + 5)2
4x-14
It is a linear equation in x. It has a solution, which is x = -5
(4x+5)(4x+5)
(4x + 5)(4x + 5)
4x+5 = -9 4x = -9-5 4x = -14 x = -3.5
4x - 5 + 2x = 37
If: 3x+5 = 4x+1 Then: x = 4
8x+5=4x+13 4x=8 x=2 Therefore, your answer is 2.
