Question

1 ) 2 ) . 3 ) 4 ) 3x ( x - 2 ) ( x + 2 ) -x ( 3x + 3 ) . A = 3 * (x + 1) ^ 2 - (x + 3) ^ 2; B = (x - 2) ^ 2 - (x - 4) * x; M = 3 * (x + 2) ^ 2 - 3(x ^ 2 - 4); N

Answer

A + 3 9 B 4 x +4 + 4x 2x ^ 2 - 6; M = 3(x ^ 2 + 4x + y) - 3x ^ 2 + 12; 4 + N = x ^ 2 - (x ^ 2 - 1) + 5; =3x^ 2 +12x+12-3x^ 2 +12; =x^ 2 -x^ 2 +1+5=6; 12x + 24
