Question

If p = 5x and q = 3x - 1, show that 2pq =30x²-10x​

Answer 1

Explanation:

Given:

p = 5x

q = 3x - 1

We want to show that:

2pq = 30x² - 10x

First, let's find the value of pq:

pq = (5x) * (3x - 1)

= 15x² - 5x

Now, let's multiply 2pq:

2pq = 2 * (15x² - 5x)

= 30x² - 10x

So, we have shown that 2pq is indeed equal to 30x² - 10x.
