Question

Using the quadratic formula to solve x2 + 20 = 2x, what are the values of x??

These are the options

O 12/21
O 1 2 191
O 1+2,1191
O 12.191​

Answer 1

`x^2-2x+20=0\implies D=b^2-4ac<0\implies x_1,x_2\\otin\mathbb{R}`.

There are no real solutions to the quadratic equation.

Hope this helps.
