I am going to go with the assumption that your equation is
. If there is only one solution, then the equation must be a perfect square. So square
to solve for the equation in the similar form that is given.
. So the variables match up perfectly in the equation, meaning that the value of m is 6, letter choice C.

x=y
2x+3x=-5
x=-1
y=-1
Answer:
B) x = 3 or x = -5/2
Step-by-step explanation:
Solve for x over the real numbers:
2 x^2 - x = 15
Subtract 15 from both sides:
2 x^2 - x - 15 = 0
x = (1 ± sqrt((-1)^2 - 4×2 (-15)))/(2×2) = (1 ± sqrt(1 + 120))/4 = (1 ± sqrt(121))/4:
x = (1 + sqrt(121))/4 or x = (1 - sqrt(121))/4
sqrt(121) = sqrt(11^2) = 11:
x = (1 + 11)/4 or x = (1 - 11)/4
(1 + 11)/4 = 12/4 = 3:
x = 3 or x = (1 - 11)/4
(1 - 11)/4 = -10/4 = -5/2:
Answer: x = 3 or x = -5/2
The answer is C. To contradict something is to say or do the opposite of what is stated. If point S lies on plane PQR, it cannot not lie on plane PQR.
