Value of expression at x=-2 is 23/3 or \bf 7 \frac{2}{3}  \\

Given:

  •  \frac{5}{3}  {x}^{2}  + 1 \\

To find:

  • Find the value of expression, when x=-2

Solution:

Put the value x=-2 in the given expression.

 = \frac{5}{3}  {( - 2)}^{2}  + 1 \\

or

 =  \frac{5}{3}  \times 4 + 1 \\

or

 =  \frac{20}{3}  + 1 \\

or

 =  \frac{20 + 3}{3}  \\

or

\bf \frac{5}{3}  {x}^{2}  + 1 =  \frac{23}{3}  \\

Thus,

Value of expression at x=-2 is 23/3 or \bf 7 \frac{2}{3}  \\ .
