(x+5)^2 - (x-5)^2 is factored, it can be written as Ax where A is a whole number. The value of A is?
since a^2-b^2 = (a-b)(a+b)
(x+5)^2 - (x-5)^2
= (x+5-(x-5))(x+5+x-5)
= (10)(2x)
= 20x
So, A=20
thank for helping Steve.
To factor the expression (x+5)^2 - (x-5)^2, we can use the difference of squares formula, which states that a^2 - b^2 = (a + b)(a - b).
In this case, a = (x+5) and b = (x-5). So using the difference of squares formula, we can rewrite the expression as follows:
((x+5) + (x-5))((x+5) - (x-5))
Simplifying this further, we obtain:
(2x)(10)
Now, we can see that the expression can be written as 20x. Therefore, the value of A is 20.
