Answer:
Completely factor of [tex]= 25x^{2}- 144[/tex] is (5x-12)(5x + 12) .
Step-by-step explanation:
As the expression is given in the equation be as follow .
[tex]= 25x^{2}- 144[/tex]
As
12² = 144
5² = 25
By using the formula
(a² - b²) = (a - b) (a + b)
Now [tex]= 25x^{2}- 144[/tex] can be expressed as.
[tex]= (5x)^{2}- 144[/tex]
By using the formula mentioned above
= (5x-12)(5x + 12)
Therefore completely factor of [tex]= 25x^{2}- 144[/tex] is (5x-12)(5x + 12) .
