This quadratic equation has no real roots because its discriminant is less than zero.

No. It is a quartic equation. The largest power of x in a quadratic equation must be 2.

NO,because in quadratic equation highest power of a variable is 2. e.x. 4x2-20x+10=0.

use the quadratic formula. when done so the roots are z=-3, and z=-6

To find which has imaginary roots, use the discriminant of the quadratic formula (b2 - 4ac) and see if it's less than 0. (The quadratic formula corresponds to general form of a quadratic equation, y = ax2 + bx + c)A) x2 - 1 = 0= 0 - 4(1)(-1) = 4Therefore, the roots are not imaginary.B) x2 - 2 = 0= 0 - 4(1)(-2) = 8Therefore, the roots are not imaginary.C) x2 + x + 1 = 0= 1 - 4(1)(1) = -3Therefore, the roots are imaginary.D) x2 - x - 1 = 0= 1 - 4(1)(-1) = 5Therefore, the roots are not imaginary.The equation x2 + x + 1 = 0 has imaginary roots.
