Question

How do I Factor 42p⁴+9p³q²-18p²q²​

Answer 1

42p^4 + 9p^3q^2 -18p^2q^2 = p^2 (42p^2 + 9pq^2 - 18q^2)

Explanation:

To answer this, we simply look for that term that is common to all

Looking at the given expression, we can see that the term we are looking for is p^2

Thus, we have that;

42p^4 + 9p^3q^2 -18p^2q^2 = p^2 (42p^2 + 9pq^2 - 18q^2)

When we multiply the term outside the bracket with each of the terms inside, we get back the original term
