Answer 2

Step-by-step explanation:

Given :

• x = 2

To Find :

• find the value of the expression 17x + 19x² + 21x²

Solution :

$: \implies \: \: \: \sf \: \: \: \: \: \: \:17x + 19 {x}^{2} + {21x}^{2}$

Substitute all values :

$: \implies \: \: \: \sf \: \: \: \: \: \: \:17 \times 2+ 19 \times {2}^{2} + 21 \times {2}^{2} \\ \\ \\ : \implies \: \: \: \sf \: \: \: \: \: \: \:34 + 19 \times 4 + 21 \times 4 \\ \\ \\ : \implies \: \: \: \sf \: \: \: \: \: \: \:34 + 76 + 84 \\ \\ \\ : \implies \: \: \: \sf \: \: \: \: \: \: \:194$
