x2 + 4x = 1
x2 + 4x - 1 = 0
in the quadratic formula (b2+- Sqr(4ac))/2a,
a = 1
b = 4
c = -1
so x = 8 +- i

What is x2 plus 4x plus 4 equals 25?
x2+4x+4 = 25 x2+4x+4-25 = 0 x2+4x-21 = 0 (x+7)(x-3) = 0 x = -7 or x = 3
X2 plus y2 plus 4x - 2y - 5 equals 0?
No.
Solve x2 - 4x - 9 equals 0 by completing the square?
x2 - 4x - 9 = 0 ∴ x2 - 4x = 9 ∴ x2 - 4x + 4 = 13 ∴ (x - 2)2 = 13 ∴ x - 2 = ±√13 ∴ x = 2 ± √13
X2 plus 4x-6 equals 0?
Assuming that by writing that equation as a question, you mean to ask how to solve it for x, that can be done as follows: x2 + 4x - 6 = 0 x2 + 4x + 4 = 10 (x + 2)2 = 10 x + 2 = √20 x = -2 ± √20
Can you put the equation x2 plus 4x plus 10 equals 3 in the form ax2 plus bx plus c equals 0?
x^2+4x+7
2x equals x2 plus 4x-3?
2x = x2 + 4x - 3 x2 + 2x - 3 = 0 (x - 1)(x - 2) = 0
What is Y equals -3 plus 4x-x2 in standard form?
y=-x^2+4x-3
