Answer 1

Answer:

i do not know the answer but i know some examples just check it out

Step-by-step explanation:

5y + 15 = 5 × y + 5 × 3 (HCF is 5) 2 21x − 24y = 3 × 7x − 3 × 8y (HCF is 3)

= 5(y + 3) = 3(7x − 8y)

3 12ab + 18a = 6a × b + 6a × 3 (HCF is 6a) 4 5x

2 − 30x = 5x × x − 5x × 6 (HCF is 5x)

= 6a(b + 3) = 5x(x − 6)

5 −12x

2 − 3x = −3x × 4x − 3x × 1 (HCF is −3x)

= −3x(4x + 1)

6 3a

2b − 9ab2 + 15ab = 3ab × a − 3ab × b + 3ab × 5

= 3ab(a − b + 5)
