Answer:
answer is 7
Step-by-step explanation:
here , give that x = 2
so we can put the value of x in the given equation ....
so,
=3 × (x)³ - 5 × (x)² + 3
=3 × (2)³ - 5 × (2)² + 3
=3 × (2×2×2) - 5 × (2×2) + 3
=3 × 8 - 5 × 4 + 3 ( according to BODMAS rule we will first do multiplication )
=24 - 20 + 3
= 4 + 3
= 7
