Use the quadratic formula:
x = [-b +&- SQRT (b2-4ac)]/2a
where a,b,c are coefficients of the quadratic equation in the form of ax2+bx+c. So in your example a=1, b=-5, c=5
x = [-(-5) + SQRT(52-4*1*5)]/2*1 & x = [-(-5) - SQRT(52-4*1*5)]/2*1
x = [5 + SQRT (5)] / 2 & x = [5 - SQRT(5)]/2
What else can I help you with?
5x plus 3y plus z equals -29 solve this system of equation?
To solve an equation with three unknowns, x, y and z, you require 3 independent equations.
How do you solve the system of equation 5x plus y equals -7 amd 3x plus y equals 15?
5x+y=-7 3x+y=15 8=D
How do you solve 5x equals 18 plus 5x?
That equation has no solution. There is no possible number that's equal to 18 more than itself.
How do you solve the equation y plus 3 equals 5x?
You need another equation to make this a linear equation so you can solve for both variables. One equation with two variables is not enough to determine the correct answer.
What does -7x plus 7 plus -5x plus 3 plus 74x-2 equals?
you need to find the value of X first before you can solve this equation
How do you solve f of x equals x squared plus 5x plus 1?
f(x) = x2 + 5x + 1 The roots of this equation are x = -0.2087 and x = -4.7913 (approx).
What is -5x plus 3 equals -22?
It is a linear equation in the variable x. You can solve for x using algebra: -5x + 3 = -22 -5x = -25 -x = -5 x = 5
If 8X plus 5X plus 2X plus 4X equals 114 then 5X plus 3 equals?
Then x = 6 Therefore; 5x + 3 = 33 First you have to solve the value of X: 8X + 5X + 2X +4X = 114; OR 19x = 114. When you divide both sides of the equation by 19 to solve for X, you find that X = 6. Ergo, 5X + 3 = 30 + 3 = 33; hence, 5X + 3 = 33.
How do you solve 5x plus 6y equals -60?
You cannot solve 1 linear equation in 2 unknown variables. You need at least two independent equations.
5x plus 3y equals 17 5x - 2y equals -3?
Multiply the bottom equation by -1
How do you solve this equation n divided 80 equals fifty?
5x = 80
How do I solve 5x plus 2y equals 20?
If as a straight line equation: 5x+2y = 20 then y = -2.5x+10 whereas -2.5 is the slope and 10 is the y intercept
