Question

ПРЕОБРАЗУЙТЕ ТРЕХЧЛЕН В КВАДРАТ ДВУХЧЛЕНА

Answer 1

(x+y)²
(m-p)²
(a+3)²
(c-5)²
(b+8)²
(d-9)²

Answer 2

$x^2+2xy+y^2 = (x+y)^2 \ m^2-2mp+p^2 = (m-p)^2 \ a^2 +6a+9 = a^2 +2cdot 3cdot a+3^2 = (a+3)^2 \ c^2 -10c+25=c^2 -2cdot 5cdot c+5^2 = (c-5)^2 \ b^2+16b+64 =b^2 +2cdot 8cdot b+8^2 =(b+8)^2 \ d^2 -18d+81 = d^2-2cdot 9cdot d + 9^2 = (d-9)^2$
