Which of the following polynomials has zeros at x = -4 and x = 7?
1 answer:
Answer:
<em>Last option</em>
Step-by-step explanation:
<u>Roots (Zeros) of Polynomials</u>
A given polynomial P(x) is said to have a root or zero at <em>x=a</em> if <em>P(a)=0</em>.
We must find a polynomial which zeros are x=-4 and x=7. We can test each option, but let's derive the polynomial by multiplying the factors (x+4)(x-7)
So if our polynomial was
its zeros will be x=-4 and x=7
Testing x=-4
Testing x=7
