If (x+1) is a factor of `2x^(3)+ax^(2)+2bx+1`, then find the value of a and b given that 2a-3b=4.

Explanation

To solve the problem, we need to find the values of \( a \) and \( b \) given that \( (x + 1) \) is a factor of the polynomial \( 2x^3 + ax^2 + 2bx + 1 \) and the equation \( 2a - 3b = 4 \).

### Step 1: Use the Factor Theorem
According to the Factor Theorem, if \( (x + 1) \) is a factor of the polynomial, then substituting \( x = -1 \) into the polynomial should yield 0.

### Step 2: Substitute \( x = -1 \)
Substituting \( x = -1 \) into the polynomial:
\[
