hello i am solving this problem in python IDLE ? Positive root of the following equation: 34*x^2 + 68*x - 510 i wrote this >>>import math math.sqrt(34*x^2 + 68*x - 510) and press enter but it came out error...could anyone tell me where wrong, is it not sqrt ?
From where does Python get the value of x? Do you know what operator precedence is?
what kind of error msg do you get? did you define x? also make sure you got positive number in you math.sqrt().
the exercise asks to calculate the positive root of 34*x^2 + 68*x - 510, i don't know what operator precedence is i'm new to all of this, the error say "name x is not defined" so how do i define "x"
just make a line above your formula: x = 8 for example. Python use "=" to define variables. you will get there shortly...
True Man you can't use Python to solve mathematical problems without coding. use Microsoft mathematics instead.
The roots of a quadratic expression are the solutions when the equation equals zero. For this particular expression, there is one negative root and one positive root. I won't tell you what they are, as I don't know exactly what your problem is. Simply taking the square root of the expression will not do the job. To use python to find the roots, I imagine that you will need to use the quadratic formula. \[x = \left( -b \pm \sqrt{b ^{2}-4ac} \right)/2a\] Where a, b and c are the coefficients in the expression: \[ax ^{2}+bx+c\] So coefficient a = 34, b = 68 and c = -510 for this case. I hope that helps? Or has it just made you more confused. I am only beginning in this too, so I am going to take up this challenge and write some code! :)
