Answer:

x = -1/2   or x = -3

Step-by-step explanation:

2x^2 + 7x + 3 = 0

First, we try factoring the polynomial.

(2x + 1)(x + 3) = 0

It works. Now we set each factor equal to zero.

2x + 1 = 0   or   x + 3 = 0

2x = -1   or   x = -3

x = -1/2   or x = -3

Find the equation (in standard form) whose center is (5, -3) and goes through (2, 5).
yanalaym [24]
We can write this as

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

where r = radius

Plugging in the point (2,5) we have

(2-5)^2 + (5+3)^2 = r^2
r^2 =  9 + 64 = 73
so the required equation is

(x - 5)^2 + (y + 3)^2 = 73
