(a) 5
(b) a²
(c) 5a²
(d) None of the above​

Answer 1

Answer:

The answer is option (c) 5a^2

Answer 2

Answer:

The terms of the expression are 5a⁴, 10a³ and -15a².

So we'll find out greatest common factor of numerical parts first, i.e of 5, 10 and -5. It is 5.

And greatest common factor of the variable parts, i.e of a⁴, a³ and a² is a².

Therefore the required answer is 5 * a² = 5a²

Ans. (c)
