Question

solve by factorization y^2-7y-30=0​

Answer 1

Answer:

$(y + 3) \: (y - 10)$

Step-by-step explanation:

⟹ y² -7y - 30

⟹ y² - 10 y + 3y - 30 [in next step take y as common ]

⟹ y ( y - 10 ) + 3 ( y - 10 )

⟹ ( y + 3 ) ( y - 10 )

Therefore , the factorization of y² -7y - 30 is ( y + 3 ) ( y - 10 ) .
