Question

Aadoreity semnyum nya manis kayak tebuu

s² - 961 = (s+a)(s-a)
Nilai a = ?

jawaban pertama = beA
jawaban benar = beA​

Answer 1

s² - 961 = (s+a)(s-a)

s² - 961 = s ( s - a ) + a ( s - a )

s² - 961 = s² - as + as - a²

s² - 961 = s² - a²

-961 = -a²

a² = 961

a = √961

a = 31

Answer 2

Penjelasan dengan langkah-langkah:

s² - 961 = (s+a)(s-a)

√961 = √31² = ± 31

s² - 961 = s² - 31²

(s + 31)(s-31)

a = 31

semoga membantu
