Question

Find the value of the polynomial 4x² – 5x + 3 at x =
2
​

Answer 1

Answer:

9 is the answer

step by step:

4x^2 - 5x + 3

4(2^2) - 5(2) +3

4(4) - 10 +3

16 - 10 + 3

16 - 7

9

Answer 2

$\: \: \: \: \: \: \: \: \: \: \: \: \: 4 {x}^{2} - 5x + 3$

By putting the value of ‘x’ as ‘2’ the polynomial is,

$\: \: \: \: \: \: \: 4 \times {(2)}^{2} - 5 \times 2 + 3 \\ \\ = > 4 \times 4 - 10 + 3 \\ \\ = > 16 - 10 + 3 \\ \\ = > 6 + 3 \\ \\ = > \green {\boxed{9}}$
