Consider the expression ${\displaystyle -16t^2+250}$
To simplify the expression, by substitute the value of variable by given term.
So simplify as follow:
Substitute the value of variable t=2.
${\displaystyle -16t^2+250=-16\cdot {\left(2\right)}^2+250}$ [Substitute the variable.]
=-16*4+250 [Write the value of square.]
=-64+250 [Multiply them.]
=186 [Simplify the term.]
Therefore, the simplified term is 186.
