Question

On simplifying (-3y2 − 8) − (-5y2 + 1), we get

Answer 1

Answer:

$\huge{\boxed{\sf{ 2y^{2} - 9 }}}$

Step-by-step explanation:

$( - 3y^{2} - 8 ) - ( - 5y^{2}+ 1 )$

While subtracting , sign of each term of the second expression changes.

⇒$- 3y^{2} - 8 + 5y^{2} - 1$

Combine like terms : $-3y^{2}$ and $5y^{2}$

Like terms are those which have the same base.

⇒$2y^{2} - 8 - 1$

Remember : The negative integers are always added but posses the negative ( - ) sign.

⇒$2y^{2} - 9$

Hope I helped!
