Let's say "n" is a natural number. {1,2,3,4,..} To ensure we have an even number we will multiply "n" by 2. Two times any number will make an even number.
consecutive even numbers are like; 2, 4, 6, 8, 10 .. etc. Add +2 to the previous number to get the next consecutive.
1st even number = 2n
2nd even number = 2n + 2
3rd even number = 2n + 4
twice the first number (2n) is 20 more then the second (2n + 2).
2(2n) = 2n + 2 + 20
4n = 2n + 22
4n - 2n = 22
2n = 22
n = 11
Now use n = 11 to find the 3 consecutive even numbers.
1st even number = 2(11) = 22
2nd even number = 2(11) + 2 = 24
3rd even number = 2(11) + 4 = 26
22, 24, 26
Answer:
Step-by-step explanation:
consider 6x^2-8x +k
disc .=(-8)^2-4*6*k=64-24k
it has no solution if 64-2k<0
or 64<2k
or 2k>64
k>32
it has two zeros if 64-2k≥0
or 64≥ 2k
or 2k≤64
or k≤ 32
it has one zero if Disc. =0
64-2k=0
2k=64
k=32
