Answer:
x=4+√5 or x=4−√5
Step-by-step explanation:
Multiply both sides by x-4.
x2−8x+16=5
x2−8x+16−5=5−5(Subtract 5 from both sides)
x2−8x+11=0
For this equation: a=1, b=-8, c=11
1x2+−8x+11=0
x=
−b±√b2−4ac
2a
(Use quadratic formula with a=1, b=-8, c=11)
x=
−(−8)±√(−8)2−4(1)(11)
2(1)
x=
8±√20
2
x=4+√5 or x=4−√5
Answer:
Step-by-step explanation:
(x^3/x^4)^2
=(x^3×x^{-4})^2
=(x^{3-4})^2
=(x^{-1})^2
=1/x²
<h2>Answer:</h2>
2 fewer than the quotient of a and 5
(x/5)-2
