Subtract 6p² -7p +5 from 10 - 7p² + 5p
Answers
Answer:
10 - 7p² + 5p - (6p² - 7p + 5)
Now, we have to open the brackets.
⇒ 10 - 7p² + 5p - 6p² + 7p - 5
And now, we have to group the like terms together and add/subtract them.
⇒ 10 - 5 - 7p² - 6p² + 7p + 5p
⇒ 5 - 13p² + 12p
∴ The final answer is 5 - 13p² + 12p
(NOTE: Which ever term dome after the word from should be written first.
Example: Subtract 4 from 2.
Over here, the term "2" comes after the word "from", so we should write 2 at first.
⇒ 2 - 4 = -2)
Thnx and have a nice day!

Answer:
10 - 7p² + 5p - (6p² - 7p + 5) = 5 - 13p² + 12p
Step-by-step explanation:
As we know that the 2nd expression is written first and the first expression is written second. It is important to write like that especially in subtraction.
So now,
10 - 7p² + 5p - (6p² - 7p +5)
As there is a minus sign in front of the bracket the signs of the numbers inside the brackets change. So the equation will be:-
10 - 7p² + 5p - 6p² + 7p - 5
so now we have to bring the like terms together with their signs-
10 - 5 - 7p² - 6p² + 5p + 7p = 5 - 13p² + 12p
