Using the quadratic formula, plug a=2, b=3, and c=4 into the formula because the equation given can not be factored.
x= -3(+/-) radical (3^2-4*2*2)/2(2)
therefore, x= (-3+ radical 7 i) / 4
x= (-3- radical 7 i )/ 4.
the answer choice is 1.

By the remainder theorem, the remainder upon dividing a polynomial
by a linear binomial
is equal to
. Via synthetic division, we get
1 | 4 -5 6
. | 4 -1
- - - - - - - - - - -
. | 4 -1 5
which translates to
or
Indeed, when
, the first term on the right hand side vanished and we're left with 5.
<span>The simplified version or form of the radical number given, square root of 26, is already itself. This is because this radical is already in its simplest form. We can no longer factor out 26 to give us any two or more numbers that can be expressed in simpler radical form. Note that the factors of 26 are 2 and 13 only. </span>
It grows by 10% each year. multiply the number by 0.1, then add. so 0.1×2420 is 242. add 242+2420=2662.
short answer:
this years tuition is $2662.
next years tuition is $2928.
Number of exams per semester = 5
Average of first four exams = 90
Therefore,
Total of first four exams = 90*4 = 360 marks
Based on 5 exams,
Average = 360/5 = 72
