Question

find discriminate of the quadratic equation 1-x=2x²​

Answer 1

Answer:

1 – x = 2x2

2x2 + x – 1 = 0.

Compare given equation with the general form of quadratic equation, which is ax2 + bx + c = 0.

Here, a = 2, b = 1, c = –1.

Discriminant formula: D = b2 – 4ac.

= (1)2 – 4 x 2 x -1.

= 9.
