Answer: If the quadratic equation has real, rational solutions, the quickest way to solve it is often to factorise into the form (px + q)(mx + n), where m, n, p and q are integers. This is especially true where the coefficient of x2 is 1.
Example 1 - Solve x2+7x+12=0

Step -by-step explanation: the opposite of a number is the number on the other side of the numbers line eg -5 is the opposite of 5 so-12% is the opposite of 12%
Answer:-12%
Breaking apart means that you just take the tens from each number, and the ones from each number, then add them up.
The tens from your numbers are:
30 from 34
40 from 45
The ones from your numbers are:
4 from 34
5 from 45
Now, you have to add up the tens and ones separately.
30 + 40 = 70
4 + 5 = 9
Finally, you add up those 2 numbers that you got- 70 and 9
