Question

Roots of 9k^2+15k-14.??

Answer 1

Here Your Quadratic Equation is

9K²+15k–14 =O

So By Factorising to find it's root or You can say to find value of K...

So By Factorization we get ,

$= 9 {k}^{2} + 21k - 6k - 14$

$= 3k(3k + 7) - 2(3k + 7)$

$=( 3k - 2)(3k - 7)$

$= (3k - 2) = > 3k = 2 \\ k = \frac{2}{3}$

$= (3k - 7) = > 3k = 7 \\ k = - \frac{7}{3}$

Both values are applicable
