Question

Which statement about the following equation is true?

2x2 – 9x + 2 = –1

Answer 1

The discriminant is less than 0, so there are two real roots.
The discriminant is less than 0, so there are two complex roots.
The discriminant is greater than 0, so there are two real roots.
The discriminant is greater than 0, so there are two complex roots.

Answer 2

please help

Answer 3

will recieve fan and metal

Answer 4

2x2 – 9x + 2 = –1
2x^2 - 9x + 3 = 0

discriminant for ax^2 + bx + c = 0 is
b^2-4ac

so plug in a = 2, b = -9 and c = 3 into this formula and work it out

Answer 5

ok I'll start it off for you
discriminant = (-9)^2 - 4*2*3

Answer 6

alright ill get it ty
