answer me plzzzzz​

Answer 1

Answer:

3y²+4y-15

3y²+5y-9y-15

y(3y+5)-3(3y+5)

(3y+5)(y-3)

Answer 2

Answer :

• Zeros of the quadratic polynomial are 5/3 and -3 respectively.

Given :

• A quadratic polynomial 3y² + 4y - 15.

To Find :

• Zeroes of the quadratic polynomial.

Solution :

Firstly we'll write the equation

• 3y² + 4y - 15

Split the middle term

• 3y² + 9y - 5y - 15

Take common

• 3y (y + 3) - 5 (y + 3)

Arrange them together

• (3y - 5) (y + 3)

Equate with 0

______________

→ 3y - 5 = 0

→ 3y = 5

→ y = 5/3

→ y + 3 = 0

→ y = 0 - 3

→ y = -3

______________

Hence, the zeroes of the quadratic polynomial are 5/3 and -3 respectively.
