Q^2 - 125 = 0
q^2 = 125
q = +/- sqrt 125 = 11.18, -11.18
With the facts you got here, you can make the following equation:
x*(x+2)=24
x^2+2x=24
x^2+2x-24=0
Then you can use the following formula (which you might have seen before):
x = (-b +/- sqrt(b^2-4ac))/2a
where
ax^2+bx+c=0
(-2 +/- sqrt(4+96))/2
(-2 +/- 10)/2
x_1 = 4
x_2 = -6
The greatest common factor of 645 and 570 would be <u>35</u>.
Answer:
Step-by-step explanation:
The difference of the rational and and irrational number is always an irrational number.
Correct choice is B
The greatest common factor of 64 and 96 is... uhh... hmm... 32! Because 64/32 is 2, and 96/32=3. 2 and 3 have no factors in common, except 1.
The answer is 32(2+3).
This means 32*2 + 32*3
this is the same as 64+96
