how do u live with all this math in ur head

Answer 2

Step-by-step explanation:

,For adding or subtracting, you must have to put the same variable's power with second equation variable's power.

for ex:- (1+2x + 3x^2) + (3x-4-2x^2)

= (1-4)+ (2x+3x) + (3x^2 - 2x^2)

=(-3) + (5x) + (x^2)

= x^2 + 5x -3

For multiplication, you have to multipy from 1st term to all equation and then second term of all equation and so on...

for ex:- (x+3)*(x^2-3x+9)

=×(x^2 - 3x + 9) + 3(x^2 -3x + 9)

=(x^3 - 3x^2 +9x) + (3x^2 - 9x +27)

=x^3 +27

I hope u understand this...

plz mark as brainliest....
