Question

Factorise completely each of the following:
7ax²+28ay²-14a³x

Answer 1

Answer:

7*a*x*x+28*a*y*y -14*a*a*a*x

Answer 2

Answer:

Step-by-step explanation:

Given that,

7ax²+ 28ay² - 14a³x

Factors of 7ax² = 7 × a × x × x

Factors of 28ay² = 2 × 2 × 7 × a × y × y

Factors of 14a³x = 2 × 7 × a × a × a × x

∴ 7ax² + 28ay² - 14 a³x

= 7ax² - 14a³x + 28ay²

= 7a ( x² - 2a²x + 4y² ) is the answer.
