To do this, simply solve the multiplication problem:
5.4 x 6.007 = k
32.4378 = k
k = 0.1
They are +/- 5*sqrt(2)
Using the discriminant for a quadratic equation the value of k works out as plus or minus 12.
2
You cannot go beyond x = k unless you know the value of k. And in that case, the equation is solved so there is nothing further to do!
The value of k is 0
K= 18.666666
11 + 6k = 65 Subtract 11 from both sides: 6k = 65-11 6k = 54 Divide by 6 to get k: k = 54/6 k = 9
1
k = 0.1
54
-108
All we can deduce from that information is that k is a positive perfect square. Is that really the whole question? What?
They are +/- 5*sqrt(2)
K+1 is as simplified as it gets. Unless you find the value of K. You can't add a variable and number.
Using the discriminant for a quadratic equation the value of k works out as plus or minus 12.
For the equation x2- 10x - k equals 0, you can solve this by knowing that if there is only one solution then the discriminant b2 - 4ac must be equal to 0. In this equation, a is 1, b is 10 and c is k This equation becomes 100 - 4k equals 0, and k is 25.
