Ano ang posibleng sagot para sa (sqrt10-5) (sqrt10 + 2)? Paano mapadali ang sagot? Salamat sa tulong.

Sagot:

# -3sqrt10 #

Paliwanag:

Isipin ito bilang batayan # (a-b) (a + c) # at kung paano mo palawakin ito kung saan ito magiging #a (a + c) -b (a + c) = a ^ 2 + ac-ab-bc #

Kaya # (sqrt10-5) (sqrt10 + 2) = sqrt10 (sqrt10 + 2) -5 (sqrt10 + 2) = 10 + 2sqrt10-5sqrt10-10 = -3sqrt10 #

Sagot:

#color (magenta) (- 3 sqrt 10 #

Paliwanag:

#color (white) (aaaaaaaaaaaaa) ## sqrt10-5 #

#color (white) (aaaaaaaaaaa) ## xx underline (sqrt10 + 2) #

#color (white) (aaaaaaaaaaaaa) ## 10-5sqrt10 #

#color (white) (aaaaaaaaaaaaaaaa) ## + 2 sqrt 10-10 #

#color (white) (aaaaaaaaaaaaa) ##overline (10-3 sqrt 10-10) #

#color (white) (aaaaaaaaaaaaa) ##color (magenta) (- 3 sqrt 10 #
