  • TheGreatWulfbite: (4x+5)(-3x-1)=
    -12x²-19x-5
    So, you answers would be:
    A. (-16x²+10x-3) + (4x²-29x-2)
    D. (2x²-11x-9) - (14x²+8x-4)

  • Cricetus:

    Answer:

    A. C. And D. Are same

    Step-by-step explanation:

    (4x+5)(-3x-1)

    Applying distributive law

    4x(-3x-1)+5(-3x-1)

    Again applying distributive law in both the brackets

    [tex]-12x^2-4x-15x-5[/tex]

    Adding the terms having same power of x

    [tex]-12x^2-19x-5[/tex]

    1. [tex]-16x^2+10x-3+(4x^2-29x-2 ) [/tex]

    Simplifying the terms containing the same power of x

    [tex]-16x^2+10x-3+4x^2-29x-2[/tex]

    [tex]-12x^2-19x-5[/tex]

    Hence it is true

    2. [tex]3(x-5)-2(6x^2+9x+5) [/tex]

       [tex]3x-15-12x^2-18x-10[/tex]

      [tex]-12x^2-15x-25[/tex]

      False

    3. [tex]2(x-1)-3(4x^2+7x+1) [/tex]

       [tex]2x-2-12x^2-21x-3[/tex]

      [tex]-12x^2-19x-5[/tex]

    True

    4. [tex]2x^2-11x-9-(14x^2+8x-4)[/tex]

       [tex]2x^2-11x-9-14x^2-8x+4[/tex]

      [tex]-12x^2-19x-5[/tex]

    True

    5. [tex] -15x^2+9x-10+3x^2-10x-5[/tex]

    [tex]-12x^2+19x-15[/tex]

    False

    6. [tex]4x^2-13x-7-(16x^2+9x-5)[/tex]

       [tex]4x^2-13x-7-16x^2-9x+5[/tex]

      [tex]-12x^2-22x-2[/tex]

    False
