-x^2+2x-9=0 find the discriminant

- 32

Step-by-step explanation:

Given a quadratic equation in standard form, ax² + bx + c = 0 ( a ≠ 0 ), then

the discriminant is

Δ = b² - 4ac

- x² + 2x - 9 = 0 ← is in standard form

with a = - 1, b = 2, c = - 9 , so

b² - 4ac

= 2² - (4 × - 1 × - 9)

= 4 - (36)

= - 32

answer: answer is c!

ok i got to organize the

3/15 and 12/55

3*

aha

3*4 equals 12 but not

a: no

b:

8/24 12/35

no

gautie

it's c

5/18 = 25/90

5*5=25

18*5 = 90

hope that you!

one more happy customer!
