Question

5x^2-22x-15=0 . Solve by factorization method. Plz help me

Answer 1

Step-by-step explanation:

5x² - 22x - 15=0

5x² -25x + 3x - 15 = 0

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

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

Either,

5x + 3 = 0

5x = -3

x = -3/5

or,

x - 5 = 0

x = 5

hence

x= 5, -3/5 answered

Answer 2

Answer:

5x^2 - 22 x -15

5x^2 - (25 -3)x -15

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

5 x ( x - 5 ) + 3 ( x - 15)

( x - 5 ) ( 5x +3)

so,

x=5 and x= -3/5

hope it helps
