Answer:
exponent i think.
Step-by-step explanation:
P(x) - q(x) = x²-1 -5(x-1)
= x²-1-5x+5
=x²-5x+4
The decimal is about 1.1 and you can’t simplify it
This is a basic algebraic fraction question
Step 1: Factor n2-9
Step 2: Rewrite the second fraction
Step 3: Write all the numerators under the least common denominator
Step 4: Expand bracket
Step 5: Collect like terms
It's not an irrational number because the decimal is repeating. If it went on forever and never repeated then it would be an irrational number.
I think the error is that Richie thought for a number to be irrational, it just needed to repeat forever.
