Question

please solve this sum by step by step​ and i will mark as brainlist​

Answer 1

Step-by-step explanation:

x square+4x+5=0 is the quadratic equation having two different real root.

x square-1x+5x=0

(x-1) (x+5)

Answer 2

Answer:

Option c) 2x²- 3x - 9 is your answer because;

1. ∆ = 0 then it is real and equal , it has two equal roots.

-b/2a and -b/2a

2. ∆ > 0 then it is real and distinct , it has two different roots.

-b/2a + √b²- 4ac/2a and

- b/2a - √b²- 4ac /2a

3. ∆ < 0 then it is imaginary and complex ,

it has no roots ..

By this information you can understand the question...

I hope you got it❣️
