a) a²+4a+4
b) 4x²+12x+9
c) 16+16m+4m²
d) 9a²+6ab+b²
e)a²x²+10a²x+25a²
f) x do potęgi 4+4x²+4
g) 2+10√2+25=10√2+27
h) 4+4√3+3=4√3+7
i) 32+2√64+4=32+(2*8)+4=32+16+4=52
a) (a+2)² = (a+2)(a+2) = a²+2a+2a+4=a²+4a+4
b) (2x+3)² = (2x+3)(2x+3) = 4x² +6x+6x+9=4x² +12x+9
c) (4+2m)² = (4+2m)(4+2m) =16+8m+8m+4m² =16+16m+4m²
d) (3a+b)² = (3a+b)(3a+b) = 9a² +3ab+3ab+b² =9a² +6ab+b²
e) (ax+5a)² = (ax+5a)(ax+5a) = a² x² +5a² x+5a² x+25a² =a² x² +10a² x+25a²
f) (x²+2)² (x²+2)(x²+2)=x^4+2x² +2x² +4=x^4+4x² +4
g) (√2+5)² =(√2+5)(√2+5)= 2+5√2+5√2+25=10√2+27
h) (2+√3)² =(2+√3)(2+√3)=4+2√3+2√3+3=4√3+7
i) (√32+√2)²=(√32+√2)(√32+√2)=32+√64+√64+2=32+8+8+2=50
