$~~~~~~x^2 -10x +10 =0\\\\\implies x^2 -2 \cdot 5 \cdot x +5^2 -5^2 +10 = 0\\\\\implies (x-5)^2 -25+10 = 0\\\\\implies (x-5)^2 -15=0\\\\\implies (x-5)^2 = 15$

Assoli18 [71]

Answer:

Q=2

Step-by-step explanation:

hello :

the solution to the system is

{(x,y) : x-3y=4} means infinty solution

X-3y=4 ....(*)

Qx-6y=8....(**)

multiply (*) by -2

-2x+6y = -8 (***)

add (*) and (***) : (Q-2)x =0

this ie true for reals x when Q=2
