Question

solve 5x²-22x-15=0 by factorization method​

Answer 1

Answer:

=> 5x²-25x +3x -15 =0

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

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

=> x= 5 or x =-3/5

Answer 2

Step-by-step explanation:

ANSWER

By using middle term split method,

5x

2

−22x−15=0

⇒5x

2

−25x+3x−15=0

⇒5x(x−5)+3(x−5)=0

⇒(x−5)(5x+3)=0

Either x−5=0⇒x=5 or 5x+3=0⇒x=−

5
