Question

Find the missing factor. 5y^2+4y-1=(5y-1)()

Answer 1

Answer:

(y + 1 )

Step-by-step explanation:

Given

5y² + 4y - 1

Consider the factors of the product of the y² term and the y- term which sum to give the coefficient of the y- term

product = 5 × - 1 = - 5 and sum = + 4

The factors are + 5 and - 1

Use these factors to split the y- term

5y² + 5y - y - 1 ( factor the first/second and third/fourth terms )

= 5y(y + 1) - 1(y + 1) ← factor out (y + 1) from each term

= (y + 1)(5y - 1)

The missing factor is (y + 1)

Answer 2

Answer:

(5y−1)(y+1)
