8x + 15
It has two equal solutions of 2
16x2 + 8x + 1 = 0 : This factorises to (4x + 1)(4x + 1) = 0 When 4x + 1 = 0 then 4x = -1 : x = -1/4.
x2-4x+4 = 0 (x-2)(x-2) = 0 x = 2 or x = 2 It has two equal roots.
x + 4x = 05x = 0x = 0/5x = 0

x+4x+5 = 0 5x + 5 = 0 5x = -5 x = -1
x2-4x+4 = 0 (x-2)(x-2) = 0 x = 2 or x = 2 It has two equal roots.
x = -½
x + 4x = 05x = 0x = 0/5x = 0
8 + y = 4x8 + y - 4x = 4x - 4x 8 + y - 4x = 0 8 - 4x + y = 0
It is an algebraic expression in the form of: 4x+32
