Question

Представьте выражение в виде многочлена (x-1)^2 ; (3a-b)^2 ; (5z+t)^2; (5x-2y)^2 ; (6m-4n)^2; (x+c)^2 ; (a-4)^2 ; (0,2a+b)^2

Answer 1

$(x - 1) {}^{2} = x {}^{2} - 2x + 1 \ (3a - b) {}^{2} = 9a {}^{2} - 6ab + b {}^{2} \ (5z + t) {}^{2} = 25z {}^{2} + 10tz + t {}^{2} \ (5x - 2y) {}^{2} = 25x {}^{2} - 20xy + 4y {}^{2} \ (6m - 4n )^{2} = 36m {}^{2} - 48m + 16n {}^{2} \ (x + c) {}^{2} = x {}^{2} + 2cx + c {}^{2} \ (a - 4) {}^{2} = a {}^{2} - 8a + 16 \ (0.2a + b) {}^{2} = 0.04a {}^{2} + 0.4ab + b {}^{2}$
