Question

If x=k² and y=k is a solution of x-5y+6, find k. ​

Answer 1

Answer:

K=2or3

Step-by-step explanation:

X=K$x=k^{2}$

$y=k$

$x-5y+6=0\\put X=k^{2}  and Y=k\\k^{2}-5k+6=0\\k^{2} -3k-2k+6=0\\k(k-3)-2(k-3)=0\\(k-2)(k-3)=0\\k=2or3$

Answer 2

Answer:1 or 6

Step-by-step explanation: since x= k2, y= k then:

K2 - 5(k)

K2 - 5k + 6=0

Using almighty formulae:

(K - 1)(k- 6) = 0

Either;

(K-1)= 0. Or

(K+6) = 0

K - l = 0.

K = +1 or

K - 6 = 0

K = +6
