Write a quadratic equation with roots of 3/4 and -4
Vaselesa [24]

A quadratic equation given roots is solved by using the relation

{x}^{2}  - (sum \: of \: roots)x + product \: of \: roots

from the question,

sum of the root will be

\frac{3}{4}  + ( - 4) =  \frac{3}{4}  - 4

=   \frac{3 - 16}{4}

=  \frac{ - 13}{4}

and also, product of the roots will

be

\frac{3}{4}  \times ( - 4) =  - 3

now substituting the sum of roots and product of roots into the equation

{x}^{2}  - ( -  \frac{13}{4} )x - 3

=  {x}^{2}  +  \frac{13}{4} x - 3

as the quadratic equation for the root 3/4 and -4

Can someone please simplify ln e^4/8 showing me how to do it
Otrada [13]

Answer:

e ^1/2

Step-by-step explanation:

All you do is take the fraction (4/8) and just simplify that part

4 divided by 2 = 2

8 divided by 2 =4

I got 2/4 but I can simplify more

2 divided by 2= 1

4 divided by 2 = 2

Now I got 1/2

And I would just leave e alone so my answer is e ^1/2

Do you kinda get what im saying?
