49 - x2 = -(x2 -49) = - (x-7)(x+7)
divide by x -7
Answer: -(x+7) = -x-7
(8w + 7)(8w - 7)
Yes because if x2-14x+49 then it is (x-7)(x-7) when factored
7 squared = 49
27v2 - 147 = 3*(9v2 - 49) = 3*(3v - 7)*(3v + 7)
To factorize ( x^2 - 49 ), you can recognize it as a difference of squares. It can be expressed as ( (x - 7)(x + 7) ), since ( 49 ) is ( 7^2 ). Therefore, the complete factorization is ( (x - 7)(x + 7) ).
(d+7)/(d2-49)(d+7)/(d+7)(d-7)1/(d-7)
It is a difference of squares. 9x^2-49=(3x+7)(3x-7)
(8w + 7)(8w - 7)
42
well, the square root of 81 is 9, and seven squared is 49, so it wud be 40
Yes because if x2-14x+49 then it is (x-7)(x-7) when factored
pi squared
7 squared = 49
27v2 - 147 = 3*(9v2 - 49) = 3*(3v - 7)*(3v + 7)
42
This is called an inequality. If x squared is greater than or equal to 49, then x is plus or minus 7 or greater than plus 7 or less than - 7.
Seven squared = 7 x 7 = 49
