substitute in the formula
Given equation is :
We will solve this quadratic equation, using the formula:
and
Now, putting a=1 , b=6 and c =-9 we get
and
Final solutions are: and
Answer:
k = 0
Step-by-step explanation:
Explanation:-
given straight line equation is k x+(k+1)y=2......(1)
The point A(2,2) lies on the equation is
substitute x = 2 and y=2
k(2) + (k+1)(2) =2
now simplify 2 k+2 k+2 = 2
subtracting '2' on both sides , we get solution is
4 k +2 -2 = 2-2
4 k =0
k = 0
Answer:
k = 0
Step-by-step explanation:
kx + (k + 1)y = 2
2k + 2(k + 1) = 2
2k + 2k + 2 = 2
4k + 2 = 2
4k + 2 - 2 = 2 - 2
4k = 0
4k ÷ 4 = 0 ÷ 4
k = 0

Answer:
The Number is 16.
Step-by-step explanation:
Given: Number has 4 Factors.
All 4 factors are same and even.
Factor are greater than 12.
Factors can only has 2 factors that is 1 and itself or we can say factors are prime no.
We need to find this number.
We know that there is only 1 number which is even prime.
So, our required factor is 2.
And required Number = 2 × 2 × 2 × 2 = 16
Therefore, The Number is 16.
