determine the values of m in the equation 4x² - 12x + m-2 = 0, so that it has a unique solution

hollow needle Jun 30, 2024, 3:04 PM

#

Right, what have you tried?

rapid wharf Jun 30, 2024, 3:04 PM

#

tried to pass the M to the other side of the =

hollow needle Jun 30, 2024, 3:05 PM

#

What does a unique solution mean for the quadratic?

rapid wharf Jun 30, 2024, 3:05 PM

#

well delta needs to be equal to 0

hollow needle Jun 30, 2024, 3:05 PM

#

Yes

rapid wharf Jun 30, 2024, 3:06 PM

#

so what i need to do?

hollow needle Jun 30, 2024, 3:06 PM

#

Well its clear writing D=0 here gives an equation in just m

#

So...

rapid wharf Jun 30, 2024, 3:07 PM

#

ok

#

i stopped in the part of D = 144-16(m-2)

#

what should i do now?

hollow needle Jun 30, 2024, 3:20 PM

#

Read what was said...

#

rapid wharf what should i do now?

You want a unique solution... hence D=0...
