Ineed to learn how to solve 2v^2+8=50

In order to solve this, you would subtract 8 from both sides. 8 minus 8 cancels out and 50 minus 8 minus 42.

Now, the equation should read like 2v^2=42. You would then divide both sides by 2v^2. 2v^2 divided by itself by cancels out which would leave you with 42/2v^2.

hello :

70y^8 + 30y^6 = 2 ( 35 y^8 + 15y^6)

the lenght is : 35 y^8

the width is : 15y^6
