(5+2w)do pot.2

(3xdo pot.2 + 1/3y)pot.2

(p+pierwiastek z 2)pot.2

(3t+k)pot.2

(1/3z +2w)pot.2

*pot.2 ozn. do potegi 2

Answer 1

(x+3)^2 = x^2 + 6x + 9

(2x+5)^2 = 4x^2 + 20x +25

(5+2w)^2 = 25 + 20w +4w^2

(3x^2 +1/3 y)^2 = 9x^4 + 2yx^2 + 1/9 y^2

(p+√2)^2 = p^2 + 2√2 p + 2

(3t+k)^2 = 9t^2 + 6tk + k^2

(1/3z +2w)^2 = 1/9z^2 + 4/3zw+4w^2
