Answer:
x = -8 + 
62, -8 - √
62
Step-by-step explanation:
This is the exact form
Answer:
a = jd
Step-by-step explanation:
We want to solve for a given that a/d = j
To do so we want to isolate a (get a by itself )
We can do this by using inverse operations.
We would want to get rid of the d
A is being divided by d.
The inverse of division is multiplication so to get rid of the d we multiply a/d by d but whatever we do to one side we must do to the other so we multiply both sides by d
a/d * d = a
j * d = jd
we are then left with a = jd
And we are done!
(-2 = √x - 7)x² (calculate)
(-9 = √x)x² (remove the parantheses)
-9x² + √x x²
