Now, we've got some terminology to get out of the way.
Multiplicity k
If r is a zero of a polynomial and the exponent on the term that produced the root is k then we say that r has multiplicity k.
Simple zeroes
Zeroes with a multiplicity of 1 are often called simple zeroes.
For instance, the polynomial P ( x ) = x2 -10x + 25 = ( x - 5)2 will have one zero, x= 5 , and its multiplicity is 2. In some of the way we can think of this zero as happening twice in the list of all zeroes as we could write the polynomial as,
P ( x ) = x2 -10x + 25 = ( x - 5) ( x - 5)
Written down this way the term x - 5 shows up twice and each term specified the same zero, x= 5 .Saying that the multiplicity of a zero is k is only shorthand to acknowledge that the zero will take place k times in the list of all zeroes.
solve the system of equations using the substitution method. y+5x=10 -10x+3y=5
A boy can row a boat at a constant rate of 5 mi/hr in still water, as indicated in the figure. He rows upstream for 18 minutes and then rows downstream, returning to his starting p
please help me understand polynomials- i get the small problems but i dont understand larger ones

In the earlier section we looked at using factoring & the square root property to solve out quadratic equations. The problem is that both of these methods will not always work. Not
