Question

Sederhanakan bentuk aljabar berikut : a. (5 - y)² + (5y - 1)² b. (½x + 2)² + (½x - 2)² pkai cara terima kasih

Answer 1

A. (5-y)^2 + (5y-1)^2
= (25 - 10y + y^2) + (25y^2 - 10y + 1)
= 26y^2 - 20y + 26

B. (1/2 x + 2)^2 + (1/2 x - 2)^2
= (1/4 x^2 + 2x + 4) + ( 1/4 x^2 - 2x + 4)
= 2/4 x^2 + 8
= 1/2 x^2 + 8

semoga membantu

Answer 2

A. 25-10y+y^2 + 25y^2 -10y+1 26y^2-20y+26 (semua bagi 2) --> 13y^2-10y+13 b.(1/4x^2+2x+4) + (1/4x^2-2x+4) = 1/2x^2 +8 *bener ga maksudnya begini?* kalo salah maaf :(
