The coefficient of the x-term is -3. Add the square of half of that.
.. (-3/2)² = 9/4 . . . . . . the number you need to add.
x² -3x +9/4 = (x -3/2)²
_____
If the x² term has a coefficient other than 1, you need to factor that out first and deal with the remaining binomial. For example,
.. 2x² -6x = 2(x² -3x)
For this you would need to add 9/4 inside parentheses to get
.. 2(x² -3x +9/4) = 2(x -3/2)²
Of course, to keep the original value, you would need to subtract 2*(9/4) outside parentheses.
.. 2x² -6x = 2(x -3/2)² -9/2
6/ sqrt(8)=
6/sqrt(8) * sqrt(8)/sqrt(8)
6sqrt(8)/8
3/4 * sqrt(8)
3/4 * sqrt(4*2)
3/4 * sqrt(4) * sqrt(2)
3/4 *2*sqrt(2)
3/2 *sqrt(2)
5/sqrt(11) *sqrt(11)/sqrt(11)
5sqrt(11)/11
5/11 *sqrt(11)
A = a+b/2 x h
Add sides a and b then divide by 2
After that multiply by the h
Answer:
120/97
Step-by-step explanation:
When you're turning a mixed fraction into an improper fraction, you keep the denominator (bottem number) the same, but you times the numerator (top number) by the whole number (non-fraction number/left number)
6 * 20 = 120
Therefore it should be 120/97
This can not be simplified though (if I recall)
It will says divided by or took away for subtracting and put in for adding
