Yes 2,1 is a solution of this problem
One polynomial identity that crops up often in various areas is the difference of squares identity:
A2-b2=(a-b) (a+b)
We meet this in the context of rationalising denominators.
Answer:
b>5
=greater than or equal too
Step-by-step explanation:
divide -35 by -5, and since you are dividing by a negative, the sign flips
Multiply the equations by 2 and then subtitude,
