Answer:

Therefore, the value of 'a' is -9.

Explanation:

To find the value of 'a', we need to use the Remainder Theorem. According to the theorem, if a polynomial f(x) is divided by (x - p), the remainder is equal to f(p).

In this case, we have the polynomial 5x² - 2x + a divided by (x - 2), and the remainder is given as 7. So, we can set up the equation:

5(2)² - 2(2) + a = 7

Simplifying the equation, we get:

20 - 4 + a = 7

Combining like terms, we have:

16 + a = 7

To find 'a', we can subtract 16 from both sides of the equation:

a = 7 - 16

Simplifying further, we get:

a = -9

Therefore, the value of 'a' is -9.
