Question

actividades a realizar multiplicar 1) (-4²b) (-3x) 2). (5a²y) (-6x²) 3)2ax³ (8x²y-x²) 4) (a+3) (a-1) 5.dividir 54x²y²z³ entre -6xy²z³ 6.20x⁴ -5x³ - 10x² + 15x entre - 5x

Answer 1

$1) (-4^2b) (-3x) = (-16b)(-3x) =48bx\\2)(5a^2y) (-6x^2) = -30a^2x^2y\\3)2ax^3(8x^2y-x^2) = 2ax^3(8x^2y) - 2ax^3(x^2)=16ayx^5 - 2ax^5\\4) (a+3)(a-1) = a^2 +3a-a -3= a^2+2x-3\\5)\frac{54x^2y^2z^3}{-6xy^2z^3} = -9x\\6)\frac{20x^4-5x^3-10x^2-15x}{-5x} = \frac{20x^4}{-5x} + \frac{-5x^3}{-5x} + \frac{-10x^2}{-5x} + \frac{15x}{-5x} = -4x^3+x^2+2x+3$
