Answer:
I'm not 100% sure but it might be b
Step-by-step explanation:
Answer:
<h3> Yes, but only if a=0 or b=0</h3>
Step-by-step explanation:
General form is ax^2+bx+c, and to get there we need to factor using FOIL (First Outside Inside Last)
(2x-1)(x+5)
F (2x × x)= 2x^2
O (2x × 5) 10x
I (-1 × x) -x
L (-1 × 5) -5
now add them together
2x^2+10x-x-5
2×^2+9x-5
and because the equation is in the form
ax^2+bx+c b is equal to 9
Answer:
1,3,6,10,15,21,…..
These are all the sum of natural numbers upto the n
So, in this series
1st Term = 1
2nd Term = 1+2 = 3
3rd Term = 1+2+3 = 6
4th Term = 1+2+3+4 = 10
So,
Term - n = 1+2+3+….+n = n(n+1)/2
That’s your answer n(n+1)/2
Good Luck
