How do I solve x^2 = 2x + 6?

Answers

Answer 1

Answer: Work is attached....

Answer 2

Answer: x^2-2x-6=0
D = b^2 - 4ac

a= 1
b= -2
c=-6

D= -2^2 - 4 *1* -6
D = 4 +24
D= 28

x1 = -b+ $√(D)$ / 2a
x1= 2 + 5,29 / 2
x1 = 7,29/2
x1= 3,645

------------------
x2= $(-b- √(D) )/(2a)$

x2= 2- 5,29 / 2

x2=-3,29/2
x2=-1,646

Find the value of k so that the point A lies on the line given by equation.A(2, 2), kx+(k+1)y=2

Answers

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
