Q:
Select all the expressions that are equivalent to the polynomial below.(4x+5)(-3x-1)A (-16x2 + 10x - 3) + (4x2 - 29x - 2)B 3(x - 5) - 2(6x2 + 9x + 5)C 2(x - 1) - 3(4x2 + 7x + 1)D (2x2 - 11x - 9) - (14x2 + 8x - 4)E (-15x2 + 9x - 10) + (3x2 - 10x - 5)F (4x2 - 13x - 7) - (16x2 + 9x - 5)
Accepted Solution
A:
The answers are: D and C and A and E
because:Β
B 3(x - 5) - 2(6x2 + 9x + 5)=β12x^2β15xβ25
F (4x2 - 13x - 7) - (16x2 + 9x - 5)=β12x2β22xβ2
EΒ (-15x2 + 9x - 10) + (3x2 - 10x - 5)=β12x^2βxβ15
