For example: 9x2-25 = (3x-5)(3x+5) but this only applies to negative expressions it wouldn't apply to 9x2+25
a squared - b squared = (a+b)(a-b)
The answer depends on what n is. It could be the value to position rule.
If the calibration starts from the edge of the stick then it is a meter rule Basically "0" starting from the edge And if it is a meter ruler ,there is like half inch of empty space before 0
must is a modal that implies a duty or obligation which is not self imposed but by external rule or duty. ought tois a moral or self imposed obligation or duty.
Use the commutative rule in math. If you do something to one side of the equation, you must do the same to the other side. Divide both sides by 2500 to get x = 5/2500, reduce the fraction to get the answer.
This is a difference of two square, so you can apply the factoring rule for the difference of two squares.
4x2 - 36 = (2x-6)(2x+6) A very useful general rule is this : - When an algebraic expression is the difference of two squares e.g. a2 - b2 then it factorises into (a - b) (a + b).
a squared - b squared = (a+b)(a-b)
It factors into (x-3)(x+3) as it follows the difference of squares rule. However, since you gave me an expression and not an equation, I cannot solve this expression beyond this point. If x^2-9=0. Then you can see that (x-3)=0 and (x+3)=0. Thus x=-3, 3.
it has got to have six squares
The product of a number of factors can be zero only if one of them is zero.So, if a given expression is zero, you factorise it and then, by the above rule, the statement is true if any one of the factors is zero. You therefore set each factor equal to zero to find the different possible solutions.
the rule u follow is called order of operations
It is called an expression.
ILY!!
Yes.
And what is the question?If you want to factor that, first take out the common factor of 2, and put whatever remains in parentheses. Then you can use the rule to factor the difference of two squares, to factor what remains within parentheses.
