hey there, my teacher didn't explain how to find the "excluded values," and i don't know what they are. me out with these problems and show me how it works.
you : )

The excluded values are the values that the variable cannot take on because it makes the overall expression undefined.

For example, we can't have in the expression because is undefined.

For both of these problems you do the same sort of thing, with some factorization along the way:

If or , the denominator is 0 and we have an undefined expression, so these are the excluded values.

If or , we get an undefined expression.

the cost of the pair of pants is $31.95

option (a)

step-by-step explanation:

step 1:   take 2 number whose product equal to 25..

and sum of those two number are -10

step: 2 for example here if we take 5,5 are the number,,

5*5=25

and

5+5=10

but we need -10

so if we take   -5,-5

so -5*-5=25

and -5+(-5)=-10

s0

come the equation

replace -10x by these number

like -5x -5x+25

take common

x(x-5)-5(x-5)=0

(x-5)(x-5)=0
