[t- 2/3] [t+ 3/5] what is this ans

​

Answer 1

Step-by-step explanation:

(t-2/3)(t+3/5)

=+(t-2)(t+3)/15

=

Answer 2

Explanation:

$= >[ t - \frac{2}{3} )(t + \frac{3}{5} ]$

$= > t[t + \frac{3}{5} ] - \frac{2}{3} [t + \frac{3}{5} ]$

$= > [ {t}^{2} + \frac{3}{5} t]- \frac{2}{3} t - \frac{6}{15} t$

$= > \frac{5 {t}^{2} + 3t }{5} - \frac{10t - 6t}{15}$

L.C.M of 5 and 15 is 15 :-

$\begin{array}{r | l}5 & 15 \\\cline{1-2} 3&3 \\\cline {1-2}&1\end{array}$

$= > \frac{3[5 {t}^{2} + 3t] - 10t - 6t}{15}$

$= > \frac{15 {t}^{2} + 9t - 10t - 6t }{15}$

$= > \frac{15 {t}^{2} - 7t }{15}$

We see that the variable't' is common in both terms so take common :-

$\bold{= > \frac{t(15t - 7)}{15}}$
