49 - x2 = -(x2 -49) = - (x-7)(x+7) divide by x -7 Answer: -(x+7) = -x-7
7 x 7 = 49
It is: (x-7)(x+7) when factored
7 squared = 49
Yes because if x2-14x+49 then it is (x-7)(x-7) when factored
It is a difference of squares. 9x^2-49=(3x+7)(3x-7)
(x - 7)(x2 + 7x + 49)
There's a formula for the "difference of squares." If your question was x2 - 49, the answer would be (x + 7)(x - 7). In your case, substitute the square root of 47 for the 7 in my example.
7 squared and 11 squared have no common factor greater than 1.
49 - x2 = -(x2 -49) = - (x-7)(x+7) divide by x -7 Answer: -(x+7) = -x-7
150x2 - 294 = 6*(25x2 - 49) The expression in the brackets is a difference of two squares, so: 6*(5x - 7)*(5x + 7)
-7 squared, which would be -49.
7 x 7 = 49
It is: (x-7)(x+7) when factored
7 squared = 49
Yes because if x2-14x+49 then it is (x-7)(x-7) when factored
7 squared can be expressed as a product of the same factor by multiplying 7 by itself. Therefore, 7 squared can be written as 7 x 7.
