My answer would be 10(x - 3)^2 where the "^2" means that 2 is an exponent printed
as a superscript, above the line.
The English phrase is ambiguous unless you agree to some convention about the way that
"square" is applied you can not tell what is to be squared. Is it the 3 , is the quantity
(x-8) or the whole thing, 10(x-8) to be squared.
In the first case , the answer would be 10(x-3^2)
The second case is my answer above
The third case would be (10(x-3))^2 .
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)<-----
2x squared minus 4
No, unless "a" happens to be equal to 0, or to 1.
hello
(9y+2z)(y-3z)
x = 1
This expression factors as x -1 quantity squared.

x = ? 42 = x squared minus x
