Difference of squares gives which complex factors for the expression x^2+13a. (x - i sqr 13)(x - i sqr 13)b. (x + 13i)^2(X - 13i)^2c.(x + i sqr 13)(x - i sqr 13)d. (x + 13i)(X - 13i)ASAP pls
Accepted Solution
A:
The Given Expression is : → x² + 13 = x² + (√13)²= x² - ( i √13)² As , i²= -1 because , i = √-1= (x - i√13)(x +√13) → Using the formula , A² - B² = (A-B)(A+B)Out of the four options Given : Option C →(x - i√13)(x +√13) is true regarding the expansion of function x² + 13.
