Question

answer and check the solution ​

Answer 1

Answer:

(t+5^2)(t-5^2)

(t+25)(t-25)

t^2 - 25^2 {(a+b)(a-b) = a^2 - b^2}

t^2 - 625 = 0

t^2 = 625

t = +-√625

t = +-25

Answer 2

Step-by-step explanation:

(t + s²)(t - s²)

= t² - s⁴. [ a² - b² = (a+b)(a-b) ]

checking the solution =

(t + s²)(t - s²)

= t² - s²t + s²t - s⁴

= t² - s⁴
