Explicación:
1. (2x³) · (5x³) =
=2x³*5x³
=2*x³*5*x³
=(2*5)*(x³*x³)
=10*x⁶
=10x⁶
2. (12x³) · (4x) =
=12*x³*4*x
=48*x⁴
=48x⁴
3. 5 · (2x²y³z) =
=10x²y³z
4. (5x²y³z) · (2y²z²) =
=10x²y⁵z³
5 (18x³y²z5) · (6x³yz²) =
=108x⁶y³z⁷
6 (-2x³) · (-5x) · (-3x²) =
=(−2)*x³*(−5)*x*(−3)*x²
=−30*x⁶
=−30x⁶
División monomios
1. (12x³) : (4x) =
= 12x³/4x
= 12x² /4
=3x²
2. (18x6y²z5) ÷ (6x³yz²) =
= 18x⁶y²z⁵ /6x³yz²
= 18x³yz³ /6
=3x³yz³
3. (36x³y7z4) : (12x²y²) =
= 36x³y⁷z⁴ /12x²y²
= 36xy⁵z⁴ /12
=3xy⁵z⁴
Multiplicación de polinomios
1. (x + 1) (x - 2)
=(x+1)(x+−2)
=(x)(x)+(x)(−2)+(1)(x)+(1)(−2)
=x²−2x+x−2
=x²−x−2
2. (- 5x - 1) (x + 1)
=(−5x+−1)(x+1)
=(−5x)(x)+(−5x)(1)+(−1)(x)+(−1)(1)
=−5x²−5x−x−1
=−5x²−6x−1
3. (-x - 1) (-2x + 3)
=(−x+−1)(−2x+3)
=(−x)(−2x)+(−x)(3)+(−1)(−2x)+(−1)(3)
=2x²−3x+2x−3
=2x²−x−3
4. (x – 9y)(x + 7y)
=(x+−9y)(x+7y)
=(x)(x)+(x)(7y)+(−9y)(x)+(−9y)(7y)
=x²+7xy−9xy−63y²
=x²−2xy−63y²
5. (2x – y)2x
(2x−y)(2)x
=4x²−2xy
División de polinomios
(x4 - 2x3 -11x2 + 30x -20) ÷(x2 + 3x -2)
= x4−2x³−11x²+30x−20 /x²+3x−2
