Find the polynomial. {5} is the solution set of A) x^2-5x+25=0 B)x^2+10x+25=0 C)x^2-10x+25=0 D)x^2+5x+25=0
2 answers:
Answer:
option:C
Step-by-step explanation:
A) on putting x=5 in equation we have that the equation is not equal to 0 it gives the value 25. so {5} is not a solution set of A.
B) on putting x=5 in the equation we have the equation is not equal to 0 it gives the value 100. so {5} is not a solution set of B.
C)on putting x=5 in the equation , the equation gives the value 0. so {5} is a solution set of C.
D)on putting x=5 in the equation equation does not give the value zero it gives 75. so {5} is not a solution set for D.

A system of equations with infinitely many solutions is a system where the two equations are identical. The lines coincide. Anything that is equal to 
will work. You could try multiply the entire equation by some number, or moving terms around, or adding terms to both sides, or any combination of operations that you apply to the entire equation.
You could multiply the whole thing by 4.5 to get
. If you want, you could mix things up and write it in slope-intercept form: 
. The point is, anything that is equivalent to the original equation will give infinitely many solutions x and y. You can test this by plugging in values x and y and seeing the answers!
