Your Answers are : a) D b) C
A quadratic equation is an equation of the form ax^2 + bx + c =0.
Given the equation: -2 = -x + x^2 - 4, we write it in the form of a standard quadratic equation as follows:
x^2 - x - 4 + 2 = 0
x^2 - x - 2 = 0
Comparing this with the standard quadratic equation gives that a = 1, b = -1 and c = -2
Therefore, the correct substitution of the values of a, b and c from the given equation into the quadratic formular is: <span>x = [-(-1) + or - sqrt((-1)^2 - 4 x 1 x -2)] / (2 x 1)</span>
Step-by-step explanation:
slope = -6 -3/-2 - -5 = -9/3 = -3
y = mx+b
y = -3x - 2/3
