To find the values of \( a \) and \( b \) for the polynomial \( f(x) = 2x^3 - 5x^2 + ax + b \) given that \( x = 2 \) and \( x = 0 \) are roots, we can follow these steps: ### Step 1: Identify the roots Since \( x = 0 \) and \( x = 2 \) are roots, we can denote the third root as \( r \). The polynomial can be expressed in terms of its roots: \[ f(x) = k(x - 0)(x - 2)(x - r) \] where \( k \) is a constant. ...
