Equations have solutions. I'll assume that's x^2 - 4x + 41 = 0 since this website can't reproduce plus or equals signs in questions. That doesn't factor neatly. Using the quadratic formula, we find two imaginary solutions: 2 plus or minus i times the square root of 37
x = 8.082762530298219i
x = -4.082762530298219i
where i is the imaginary square root of -1
no its is x^2-4x=41

Find three consecutive odd numbers such that the sum of their squares is a four-digit with all four digits the same?
the three numbers are: x - 2, x, x+2 the sum of their squares: (x-2)2+ x2 + (x+2)2 = x2 - 4x + 4 + x2 + x2 + 4x + 4 = 3x2 + 8 = n*1111 n= 1,2,3 ... 9 x= sqrt((n*1111 - 8)/3) n = 5, so x = 43 or -43 and the numbers are: -45, -43, -41 or 41, 43, 45
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 - 4x - 29 equals -10?
Assuming that by expressing that equation as a question you're looking to solve for x: x2 - 4x - 29 = -10 x2 - 4x + 4 = 23 (x - 2)2 = 23 x - 2 = ± √23 x = 2 ± √23
What is 4x-x2?

Solve by factoring x2 10x -16?
Given: x2 + 10x - 16 Let: x2 + 10x - 16 = 0 x2 + 10x - 16 = 0 ∴ x2 + 10x + 25 = 16 + 25 ∴ (x + 5)2 = 41 ∴ x = -5 ± √41 ∴ x2 + 10x - 16 = (x + 5 + √41)(x + 5 - √41)

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
How do you solve the limit as x approaches zero of 1 over x minus 4 plus 1 over x plus 4 all over x?
Limx→0 [ 1 / (x - 4) + 1 / (x + 4) ] / x = Limx→0 1 / (x2 - 4x) + 1 / (x2 + 4x) = Limx→0 (x2 + 4x) / (x4 - 16x2) + (x2 - 4x) / (x4 - 16x2) = Limx→0 (x2 + 4x - 4x + x2) / (x4 - 16x2) = Limx→0 2x2 / (x4 - 16x2) = Limx→0 2 / (x2 - 16) = 2 / (0 - 16) = -1/8
