if α is a root of the equation 2x^2-3x+3=0 then 4α^2-6α+3=?
if α is a root of the equation 2x^2-3x+3=0 then 4α^2-6α+3=?
if α is a root of the equation 2x^2-3x+3=0 then 4α^2-6α+3=?
如下:
如果α是方程 2x^2-3x+3=0的一个根,求4α^2-6α+3
因为α是方程 2x^2-3x+3=0的一个根,
所以2α^2-3α+3=0
2α^2-3α=-3
4α^2-6α=-6
4α^2-6α+3=-3
α is a root of the equation 2x^2-3x+3=0
=>
2α^2-3α+3 =0
4α^2-6α+6 =0
4α^2-6α+3 =-3
if α is a root of the equation 2x^2-3x+3=0 then 4α^2-6α+3=?
