Ginger was asked to solve 25x2−196=0 by factoring using the difference of squares pattern. What is/are the correct solution(s)?(1 point) Responses
x=145
There is no solution for x because the difference of squares pattern does not apply. T
x=−145 , x=145
x=19625

The correct solution is x=-145, x=145.
you guys really need to learn how to type fractions.
25x^2 - 196 = (5x-14)(5x+14)
so the roots are 14/5 and -14/5
25x^2 - 196 = (5x-14)(5x+14)
so the roots are 14/5 and -14/5
Apologies for the confusion. You are correct, the factored form of the equation is (5x-14)(5x+14) = 0. Therefore, the roots are x = 14/5 and x = -14/5. Thank you for pointing out the mistake.
