Answer:
5²x²- 49
Factoring: 25x2-49
A difference of two perfect squares, A²- B²can be factored into (A+B) • (A-B)
Proof : (A+B) • (A-B) =
A²- AB + BA - B²=
A² - AB + AB - B² =
A²- B²
25 is the square of 5
49 is the square of 7
x²is the square of x¹
(5x + 7) • (5x - 7)
-7 and -11 are like terms put them together also 15 and -6
