Answer:
A rational expression is when the numerator and the denominator are polynomials. An example is 5/x − 2
Y=6X+9 the A is #1
all you need to do is simp the equation
Answer:
(5, 1)
Step-by-step explanation:
-4+6-1=1.
Answer:
b =± 5 sqrt(3)
Step-by-step explanation:
f(b) = b^2 – 75
To find the roots set the equation equal to zero
b^2 -75 =0
Add 75 to each side
b^2 – 75+75 = 0+57
b^2 = 75
Take the square root of each side
sqrt(b^2) = ±sqrt(75)
b = ±sqrt(3*25)
We know that sqrt(ac) = sqrt(a) sqrt(c)
b = ±sqrt(3)*sqrt(25)
b =± 5 sqrt(3)
