Question

Simplify (3b2 – 2b + 3) – (5b2 + 4b – 2)

Answer 1

8b2 – 6b + 5

8b2 – 2b + 5

–2b2 – 6b + 5

–2b2 – 2b + 5

Answer 2

(3b^2 – 2b + 3) – (5b^2 + 4b – 2)


3b^2 – 2b + 3 – 5b^2 - 4b + 2


(3b^2– 5b^2)+(-2b-4b)+(3 + 2)


-2b^2-6b+5



So the answer is -2b^2-6b+5

Answer 3

Okaye thanks

Answer 4

I have forgotten how to add :'(

Answer 5

What is the slope of the line which passes through (2, 6) and (0, 2)?

Answer 6

m = (y2-y1)/(x2-x1)



m = ( 2- 6)/(0-2)



m = (-4)/(-2)



m = 2



So the slope of the line that passes through the two points is 2
