-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

£56

step-by-step explanation:

u divide 24 by 3 and u get 8 so if u do 8 time 7 or 8+8+8+8+8+8+8 u get 56 and 56 divided by 7 is 8.
