Question

Solve each of the quadratic equations below and describe what the solution(s) represent to the graph of each.
y = x^2 + 3x + 2
y = x^2 + 2x + 1

Answer 1

try factoring each one, the location where the function crosses the x axis is your answers

Answer 2

I believe they are 2 solutions

Answer 3

you can also solve this by using the quadratic formula
\[x=\frac{ -b \pm \sqrt{b ^{2}-4ac} }{ 2a }\]

Answer 4

yes either method with work in this case, since these quadratics are factorable.

Answer 5

y = y
x^2+3x + 2 = x^2 + 2x + 1
3x + 2 = 2x + 1
x = -1
y = 0

So they intersect at the point(-1,0)

Answer 6

is that right?

Answer 7

is this a system of equations?

Answer 8

on what they have in common
