Помогите, пожалуйста

Answer 1

 $intlimits^2_0 {(6x^2-12x+1)} , dx=2x^3-6x^2+x bigg|_0^2=2*8-6*4+2=10-24=-6\intlimits^2_{-1} {(10x+ frac{3}{x^4} )} , dx=5x^2- frac{1}{x^3} bigg|_{-1}^2=20- frac{1}{8} -(5+1)=14- frac{1}{8}= frac{111}{8} \intlimits^1_{-2} {(5+6x-12x^2)} , dx=5x+3x^2-4x^3 bigg|_{-2}^1=5+3-4-(-10+12+32)=4-34=-30$
