A) 3x(1 - 2x)(2x + 1) = 3x - 12x^3
б) 2x(2 - 3x)(3x + 2) = 8x - 18x^3
в) 2x^2(4x^2 - 3)(3 + 4x^2) = 32x^6 - 18x^2
<span>г) 3x^3(2x^2 + 5)(5 - 2x^2) = 75x^3 - 12x^7<u /></span>
15,7( x + 17,5 ) = - 2
X + 17,5 = - 2 : ( 157/10 )
X + 17,5 = - 20/157
X = - 20/157 - 17 1/2
X = - 40/314 - 17 157/314
X = - 17 197/314
