Explanation:

 =  > 6 {t}^{2}  - 19t - 7 = 0

=>It is in the form of a quadratic equation \bold{a {x}^{2}  + bx + c}

We factorise it to find the roots :-

How to factorise..??

step1: Multiply the constant term coefficient of x square.suppose we obtain 'z' after multiplying

step 2:Think of a number whose sum and product makes the 'z'

step 3: now split the middle term by that number which you think.

step 4:At last take common and compare with equal to 0 we obtain the roots .

 =  > 6 {t}^{2}  - 21t + 2t - 7 = 0

 =  > 3t(2t - 7) + 1(2t - 7)

 =  > (3t + 1)(2t - 7) = 0

 =  > 3t + 1 = 0

t =  -  \frac{1}{3}

 =  > 2t - 7 = 0

 t =  \frac{7}{2}

Hence ,the roots are :\bold{\red{t =  -  \frac{1}{3} }} ,\bold{\red{ t =  \frac{7}{2} }}
