Question

t²-20t +100 =0 what's the t​

Answer 1

Answer:

▪︎Given -:

${t}^{2}-20t+100=0$

▪︎To find -:

$\textsf{Value of t at the following equation}$

▪︎Concept -:

First find the -20t value . And then which the answer will come just find it square to root to find the value of t .

▪︎Solution -:

$\Rightarrow{{t}^{2}-20t+100=0}$

$\Rightarrow{{t}^{2}-20t=-100+0}$

$\Rightarrow{{t}^{2}-20t=-100}$

$\Rightarrow{{t}^{2}=\dfrac{-100}{-20}}$

$\Rightarrow{{t}^{2}=5}$

$\Rightarrow{t=\sqrt{5}}$

$\Rightarrow{t=2.236(approx)}$

▪︎Answer -:

So , the value of the t of this equation is 2.236 (approx) .
