An expression is defined as a set of numbers, variables, and mathematical operations. The zeroes of the b(x) will be (5/4) and (-5/4).
<h3>What is an Expression?</h3>
In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.
The solution for the expression b(x) can be written as,
b(x)=16x²-25
b(x)= (4x)² - 5²
b(x)=(4x-5)(4x+5)
The zeroes of the b(x) will be (5/4) and (-5/4).
Hence, The zeroes of the b(x) will be (5/4) and (-5/4).

Eexplanation:
16. Suppose the roots are α and kα. Then we can write the equation as ...
a(x -α)(x -kα) = 0
ax² -ax(α +kα) +akα² = 0
Comparing to the original equation, we can equate coefficients to get ...
Solving the first for α gives ...
α = -b/(a(1+k)
Substituting into the second, we have ...
c = ak(-b/(a(1+k)))²
Multiplying by a(1+k)², we get ...
(1+k)²ac = kb²
Using k=2 gives ...
9ac = 2b² . . . . . as required
__
17. Using the previous result with k=1 (equal roots), we have ...
(1+k)²ac = kb²
4ac = b² . . . . . for k=1
______
<em>Additional comment</em>
We observed that the problems were similar, but had different factors relating the roots. So, we elected to solve the general case, then fill in the specific values for the two problems.
Answer:
successful odds are a and c
