i think the answer is 1 X2+2xX-1 X=1 x times x = 1 plus (X times x) = 1 1+1 equals 2 minus one = 1
Whoever above is, is wrong. the actual answer is X^(2)+2X-1: The part showing '^(2)' means to the power of two or squared on a computer.
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)<-----

Two plus 3 minus 2 times 1 squared plus 4 times 16 squared minus 4 times 2 is equal to 1,019.
81 x 2 - 16 = 146

It is "a squared minus eighteen b".
3(x - 2)(x + 2)
(x squared plus the square root of 2) times (x squared minus the square root of 2).
To simplify the expression 3b^2 - 3b, we first factor out the common factor of 3b. This gives us 3b(b - 1), where b - 1 is the simplified form of the expression. This expression represents the difference between 3 times the square of a variable b and 3 times the variable b.

Well, isn't that a lovely little equation we have here! To simplify 2x squared minus 2x, we can factor out the common factor, which is 2x. So, the expression simplifies to 2x(x - 1). Just like painting a happy little tree, it's all about finding the beauty in the simplicity of things.
Two plus 3 minus 2 times 1 squared plus 4 times 16 squared minus 4 times 2 is equal to 1,019.
