factor it
You can calculate a value if you assign a value to variable "x".
It is a quadratic equation in the variable x.
9 plus 16=25 3 squared is the same as 3 times three and 4 squared is the same as 4 times 4 3 times 3 + 4 times 4 9 plus 16 = 25
2m^2 - 8 -First you should factor out a two. --> 2(m^2-4) -You now have something squared minus something else squared; You have m squared minus 2 squared. Whenever you have something squared minus something squared as you do in this case, there is a simple rule to remember: You can reduce that expression into the quantity of the square root of the first number or variable plus the square root of the second number or variable Times the quantity of the square root of the first number or variable minus the second number or variable squared. --> In the case of your expression: ----> 2(m+2)(m-2)<-----
Because you are just adding the same variable to itself, the variable does not change. in the same way that 2 + 2 is 4, 2x2 + 2x2 is 4x2.
x2 + 8x2 = 9x2
Assuming the thing is as written and there are no brackets missed out then it is just 4 squared times 3 = 16x3=48.
Why don't you figure it out yourself
p2 + p2 + p3 = 2p2 + p3 because you can add the two variables that match, while you leave the different variable alone.

Two plus 3 minus 2 times 1 squared plus 4 times 16 squared minus 4 times 2 is equal to 1,019.
