Hello,
|x+4|=3x-5
if x+4>=0 then
|x+4|=x+4
x+4=3x-5
2x=9
x=9/2
else
x+4<0 : x<-4
|x+4|=-(x+4)
-(x+4)=3x-5
-x-4=3x-5
4x=1
x=1/4 : to exclude since x<-4
end if
Only one solution : x=9/2
ANSWER B.
X^2 -6x +1 = 0
a=1
b = -6
c = 1
Use the quadratic formula
x = [-b +- sq root (b^2 -4ac)] / 2a
x = [--6 +- sq root (36 - 4)] / 2
x = [ 6 +- sq root (32)] / 2
sq root (32) = 5.657
x1 = [ 6 + 5.657] / 2
x1 = 11.657 / 2
x1 =

5.8285
</span>

x1 = 5.82 (to nearest tenth)
x2 = [ 6 - 5.657] / 2
x2 = .343 / 2
x2 = .1715
x2 = .2 (to nearest tenth)
Answer:
With a degree 2 are called quadratic equations.
Hope I Helped
Hello,
