Question

solve
$5x { }^{2} - 22x - 15 = 0$
​

Answer 1

Step-by-step explanation:

5x^2 - 25 x +3x -15 =0

5x( x-5) + 3(x-5) = 0

(x-5) (5x+3) =0

x= 5,-3/5

Answer 2

Answer:

${5x}^{2} - 22x - 15 = 0 \\ = > {5x}^{2} - (25 - 3) x - 15 = 0 \\ = > {5x}^{2} - 25x + 3x - 15 = 0 \\ = > 5x(x - 5) + 3(x - 5) = 0 \\ = > (x - 5)(5x + 3) = 0 \\ \: \: \: \: \: \: \: \: \: \: \: \: \: x - 5 = 0 \\ = > x = 5 \\ \: \: \: \: \: 5x + 3 = 0 \\ = > x = \frac{ - 3}{5}$

Hope it will help you....⤴️
