Question

Find the sum: (3x^2+5x-8) + (5x^2-13x-5) Help plspls

Answer 1

For sum you can sum same ones !
same have same words and powers .
for example :
X^2 and 2X^2 are same .
x and x^2 are not .
in this question you can sum :
3x^2 & 5x^2
+5x & -13x
-8 & -5
Together ;)
(3x^2+5x-8) + (5x^2-13x-5) = (3x^2+5x^2)+(5x-13x)+(-5-8) = (3+5)x^2+(5-13)x-5-8
can you answer now ?!;)
