For what value(s) of k will the function y=6x^2-8+k have: a) one zero b) two zeros c) no zeros *this is not multiple choice*

Step-by-step explanation:

Hello, please consider the following.

And the we know that if the discriminant is

***** < 0, meaning 8-3k<0, meaning

then, there is no real solution.

***** , meaning

There is 1 solution.

***** > 0, meaning

There are 2 solutions.

Thank you

PS: To give more details...

i found two solutions,   n = 2 • ± √3 = ± 3.4641

step-by-step explanation:

step-by-step explanation:

given perimeter: 28cm

length: 9cm

atp,

2(l+w)=p of the reactangle

2(9+x)=28

18+2x=28

2x=28-18

x=10/2

x=5

therefore width is 5 cm
