Question

Как возвести в квадрат?
(а-1)^2
(х-5)^2
(2y+3)^2
(3х+2y)^2
(2a+7)^2
(0,5х+1)^2
(0,1-2c)^2
(х^2-1)^2
(a^3+b^2)^2

Answer 1

$a^{2} +1 a^{2} +25 4 y^{2} +9 3 x^{2} +4 y^{2} 4 a^{2} +49 0,25 x^{2} +1 0,01-4 c^{2} x^{4} +1 a^{6} + b^{4}$

Answer 2

(a-1)^2=a^2-2a+1
(x-5)^2=x^2-10x+25
(2y+3)^2=4y^2+12y+9
(3x+2y)^2=9x^2+12xy+4y^2
(2a+7)^2=4a^2+28a+49
(0,5x+1)^2=0,25x^2+x+1
(0,1-2c)^2=0,01-0,4c+4c^2
(x^2-1)^2=x^4-2x^2+1
(a^3+b^2)^2=a^6+2a^3b^2+b^4
