Question

a)(16x²-5x+13)-(13x²+14x-15)=.
b)(17x²-5x+13)+(3x²+15x+14)=.
c)(14x²+5x+17)+(5x²+14x-15)=
d)(17x²-8x+14)-(6x²-2x-11)=.
e)(-14x²+7x+5)-(12x²+6x+4)+(13x²+4x-5)=

Answer 1

a)(16x²-5x+13)-(13x²+14x-15)=.
16x²-5x+13-13x²-14x+15=
3x²-19x+28

b)(17x²-5x+13)+(3x²+15x+14)=.
17x²-5x+13+3x²+15x+14 =.
20x²+10x+27

c)(14x²+5x+17)+(5x²+14x-15)=
14x²+5x+17+5x²+14x-15) =
19x²+19x+2

d)(17x²-8x+14)-(6x²-2x-11)=.
17x²-8x+14 - 6x²+2x+11 =
11x²-6x+25


e)(-14x²+7x+5)-(12x²+6x+4)+(13x²+4x-5)=
-14x²+7x+5-12x²-6x-4+13x²+4x-5 =
-13x²+5x-4
Boa sorte
