Quadratic formula to find the zeros <br> b^2-4b+4=0

Lunna [17]

Answer:

Step-by-step explanation:

Remark

I don't think you need the quadratic formula for this equation. It just factors into (b - 2)(b - 2), but I'll do it because you requested it.

Formula

$\text{x = }\dfrac{ -b \pm \sqrt{b^{2} - 4ac } }{2a}$

Givens

a = 1

b = - 4

c = 4

Solution

x = - - 4 +/- sqrt((-4^2) - 4*1*4)

====================

2*1

x = 4 +/- sqrt (16 - 16)

==========

x = 4/2

x = 2

There are 2 roots but both of them are the same. Some teachers say there is only 1 root. I'm in that group.

The formula for converting from Celsius to Fahrenheit temperatures is F=9/5C+32

umka2103 [35]

Both the original and the inverse are functions because for each value of C there is a unique value of F and vice-versa.

i.e.
<span>B. Original is a function; inverse is a function </span>
