Answer:
After completing the square the expression is (x-2)^2 -12 =0 and real solution are x = 5.46 and x = -1.46
Step-by-step explanation:
We need to complete the square:
x^2 − 4x − 8 = 0
x^2 -2(x)(2)+(2)^2 -8 -4 =0
(x^2 -4x +4) - 12 = 0
(x-2)^2 -12 =0
Now, finding the value of x
(x-2)^2 -12 =0
(x-2)^2 = 12
taking square root on both sides

So, After completing the square the expression is (x-2)^2 -12 =0 and real solution are x = 5.46 and x = -1.46
The answer is f(x)=x²+2x when evaluated with -3 gives you the value of 3
Y-y1=m(x-x1) for slope=m
point is (x1,y1)
pont s (7,4)
slope is 6
x1=7
y1=4
y-4=6(x-7)

I don’t use property’s but u know 8 is the identity property
Answer:
-10h+8
Step-by-step explanation:
First, let's open the brackets:
-6h-13+21-4h (two -'s make a +)
This is equal to -10h + 8
