$\pink{⊱⋅ ─────────────────── ⋅⊰}$

$f(x) = 2x {}^{3} - 3x {}^{2} + ax + b$

$f(0) = 2(0) {}^{3} - 3(0) {}^{2} + a(0) + b = 0$

$\boxed{b = 0}$

$\pink{⊱⋅ ─────────────────── ⋅⊰}$

$f(x) = 2x {}^{3} - 3x {}^{2} + ax + b$

$f(1) = 2(1){}^{3} - 3(1){}^{2} + a(1)+ b$

$2 - 3 + a + b = 0$

$a + b =1$

putting value of b

$a + b = 1$

$a + 0 = 1$

$\boxed{a = 1}$
