1.(x+4)^2 2.(3x-5)^2 3.(3y+4)^2 4.(4y-5)^2 5.(2m-1/2)^2 6(4m+1/m)^2 Jawab yant benar..thanks.

1) (x+4)² = x²+8x+16
2)(3x-5)² = 9x²-30x+25
3)(3y+4)² = 9y²+24y+16
4)(4y-5)² = 16y²-40y+25
5)(2m-1/2)² = 4m²-2m+1/4
6)(4m+1/m)² = 16m² + 8 +1/m²
disamain penyebutnya
16m² + 8 +1/m²
= (16m^4 + 8m² +1) per m²

1. x^2+8x+16
2.9x^2-30x+25
3.9y^2+24y+16
4.16y^2-40y+25
5.4m^2-2m+1/4
6.16m^2 + 8 + 1/m^2
