Answer: 6,960,000

Steps: (7 × 10⁶) - (4 × 10⁴)

Remove parentheses: 7 × 10⁶ - 4 × 10⁴

7 × 10⁶ = 7,000,000

4 × 10⁴ = 40,000

7,000,000 - 40,000 = 6,960,000

When p2 – 4p is subtracted from p2 + p – 6, the result is 5p-6 To get p – 9, subtract

$(p^{2} + p - 6) - (x) = p - 9

$ is what is asked.

So all you need to do is a value that will result to p - 9.

x = $(p^{2} + p - 6) - p + 9$ To isolate x we just transpose the values from the other side of the equation and do the opposite operation.

Combine like terms and just copy the terms that do not have similar expressions:

p will cancel out because p - p = 0
-6 and + 9 will come together because they are like terms: -6 + 9 = 3
$p^{2}$ does not have a pair so it will remain as is. you will be left with:

$p^{2} + 3$

Let us check:

$p^{2} + p - 6$
- $p^{2} + 0 + 3$
----------------------------
$0 + p - 9$ or $p -9$
