How to get the Coeffcient value?
显示 更早的评论
Hi!
I have the following polynomial: y = 3*x^2 + 2*x + 4;
Generally, we apply the value of 'x' and get the value of y. Is it possible or how to get the 'x' if i give a certain value of 'y'?
Its obvious to have a range of values for 'x'.
Please advise.

y = 4;
xout = roots([3,2,4 - y])

This is solution of the equation y = 3*x^2 + 2*x + 4, here y = 4, i.e.
3*x^2 +2*x + 4 - y = 0
coefficients c of the polynomial:
c = [ 3, 2, 4 - y ]
and him solution
xsol = roots(c) or xsol = roots([ 3, 2, 4 - y ])
