Find an equation with a solution of x=−5 of multiplicity 1, and a solution of x=3 of multiplicity 2. Write your answer in standard form.

Question

im having a hard time putting inot standard form.

Answer 1

(x+5)(x-3)² = 0

 

to write this equation as a polynomial, you must multiply it out.

begin by squaring the binomial, and remember to express this as a trinomial (middle term will be -6x).

Then, to finish the job, multiply that trinomial by the factor x+5, as you have learned to do in prior algebra classes.
