Answer:
x-4 and x+8
Step-by-step explanation:
Factoring a quadratic equation of the form x^2+bx+c:
Divide b into two numbers p and q, so that p+q = b and p*q = c
8 + (-4) = 4 = b
8 * (-4) = -32 = c
x^2+8x-4x-32
Factor by grouping
(x^2+8x)+ (-4x-32) =
x*(x+8) + -4* (x+8) = (x-4)(x+8)
A categorical is the variable
Answer:
(x-4)^2 + (y+1) ^2 = 25
Step-by-step explanation:
We can write the equation for a circle
(x-h)^2 + (y-k) ^2 = r^2
Where (h,k) is the center and r is the radius
(x-4)^2 + (y- -1) ^2 = 5^2
(x-4)^2 + (y+1) ^2 = 5^2
(x-4)^2 + (y+1) ^2 = 25
