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

3(x - 2)(x + 2)
(x squared plus the square root of 2) times (x squared minus the square root of 2).

Two plus 3 minus 2 times 1 squared plus 4 times 16 squared minus 4 times 2 is equal to 1,019.
Tan^2
That doesn't factor neatly. Applying the quadratic formula, we find two real solutions: -8 plus or minus 4 times the square root of 30. x = 13.908902300206645 x = -29.908902300206645
81 x 2 - 16 = 146
