Answer:
The final answers are x = 1 OR x = -3.
Step-by-step explanation:
Given the equation is x^2 -3 = -2x
Rewriting it in quadratic form as:- x^2 +2x -3 = 0.
a = 1, b = 2, c = -3.
Using Quadratic formula as follows:- x = ( -b ± √(b² -4ac) ) / (2a)
x = ( -2 ± √(4 -4*1*-3) ) / (2*1)
x = ( -2 ± √(4 +12) ) / (2)
x = ( -2 ± √(16) ) / (2)
x = ( -2 ± 4 ) / (2)
x = (-2+4) / (2) OR x = (-2-4) / (2)
x = 2/2 OR x = -6/2
x = 1 OR x = -3
Hence, final answers are x = 1 OR x = -3.

Answer:
{(-5, 3), (2, -5), (2, 9), (3, -6), (5, -3)}
Step-by-step explanation:
Start on the left side, that number is the x.
List them in pairs the left x number with the right y number it points to.
You're going to go to 50 on the y-axis and put a point there and then from 50 the slope needs to be a rise over run so go up 4 right 1:)
