Q. G(x)=(x−a)(x−b)(x−c)A polynomial function G has zeros of 5,−23, and 21. If polynomial G is defined for constants a,b, and c, then what is the value of a+b+c ?
Identify Zeros: Identify the zeros of the polynomial function G(x).The zeros of the polynomial function are given as 5, −(23), and (21). These zeros correspond to the values of a, b, and c.
Relate to Constants: Relate the zeros to the constants a, b, and c.Since the zeros of the polynomial are the values for which G(x)=0, we can say that a=5, b=−(23), and c=(21).
Calculate Sum: Calculate the sum of the constants a, b, and c.To find the value of a+b+c, we simply add the constants together: a+b+c=5+(−(23))+(21).
Perform Addition: Perform the addition to find the sum. a+b+c=5−(23)+(21)=5−1.5+0.5=5−1=4.
