Question

Find k such that the equation kx^2 + x +25k has a repeated solution.

Answer 1

equation? u mean that thing equals 0?

Answer 2

So you need to make it a perfect square, I guess.

Answer 3

Good point, josiahh, no equals sign -> no equation.

Answer 4

It's what it says on my hw. ;c

Answer 5

Can reword it as 'polynomial has repeated roots' but we don't need to get bogged down in the wording...

Answer 6

And it's saying something about using b^2 -4ac

Answer 7

I'll take it as a polynomial that has repeated roots as CliffSedge suggested. in this case just find the determinant and set it =0
1-100k=0. solve for k

Answer 8

sorry, 1-100k^2=0

Answer 9

+/- 1/10

Answer 10

yes

Answer 11

That was it, thank you o: I thought it was gonna be more drawn out than that

Answer 12

ur welcome
