Question

What is the number of real solutions?
–11x^2 = x + 11

Answer 1

no one is helping?? that s a shame!

Answer 2

Can you?

Answer 3

Find discriminant and then use quadratic formula to find the roots of equaton

Answer 4

Do you still need help with this one?

Answer 5

start with
\[11x^2+x+11=0\] then use \(b^2-4ac\) and you will see that it is negative, so no real zeros

Answer 6

So that means it has no real solutions?

Answer 7

since
\[b^2-4ac=1-4\times 11\times 11<0\] (aka negative) there will be no real solutions
the quadratic formula has a
\[\sqrt{b^2-4ac}\] in it, so if the inside part is negative, no real solutions

Answer 8

okay , thank you. Can you also tell me how to identify 3i on a graph?

Answer 9

if it is the graph of the complex plain, think of it as the point \((0,3)\)

Answer 10

okay, that makes since. Thank you
