Question

find the value of polynomial 3x³ - 5x²+3 at x=2 ... not just answer but with full details​

Answer 1

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
