Question

roots of 35x2 + 13x - 12 = 0 are​

Answer 1

Answer:

the answer is

Step-by-step explanation:

$$\begin{lgathered}35 {x}^{2} + 13x - 12 = 0 \\ 35 {x}^{2} + (28 - 15)x - 12 = 0 \\ 35 {x}^{2} + 28x - 15x - 12 = 0\\ 7x(5x + 4) - 3(5x + 4) = 0\\ (7x - 3)(5x + 4) = 0\end{lgathered}$$

Answer 2

$<hr/>$

$35 {x}^{2} + 13x - 12 = 0$

$\implies 35 {x}^{2} + 28x - 15x - 12 = 0$

$\implies 7x(5x + 4) - 3(5x + 4) = 0$

$\implies (7x - 3)(5x + 4) = 0$

$<hr/>$

$\implies7x - 3 = 0$

$\implies x = \frac{3}{7}$

$<hr/>$

$\implies 5x + 4 = 0$

$\implies x = \frac{ - 4}{5}$

Hence,

$x = \frac{3}{7} \: and \: \frac{ - 4}{5}$
