Use matrix addition to solve this equation:

C =
3 1 0
−1 2 4
9 7 −2
+
5 2 −4
1 12 3
11 3 −2
c11 =

c31 =

c22 =

i think the correct option is the second option.

x² + 3x + 7 = 0       [ax² + bx + c]

a = 1

b = 3

c = 7

quadratic formula:

    (+/- is this ±)

plug in the numbers into the variables

your answer is a

c.

step-by-step explanation:

substitution for (0,1)

y=x^2+4x+1

1=0^2+4(x)0+1

1=0+4(x)0+1

1=4(x)0+1

1=0+1

1=1

substitution for (-3,-2)

y=x+1

-2=-3+1

-2=-2
