Answer 2

Given:

3 is the zero of 5x^2 - 2x + 6a

To Find:

The value of a.

Value:

x = 3

Solution:

p(x) = 5x^2 - 2x + 6a = 0

p(3) = 5(3)^2 - 2(3) + 6a = 0

p(3) = 5(9) - 6 + 6a = 0

p(3) = 45 - 6 + 6a = 0

p(3) = 39 + 6a = 0

p(3) = 6a = -39

p(3) = a = -39/6

p(3) = a = -13/2

Answer:

The value of a is -13/2.
