Answer:
d=9.220
Step-by-step explanation:
Simplifying
3x2 + -5 = 70
Reorder the terms:
-5 + 3x2 = 70
Solving
-5 + 3x2 = 70
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '5' to each side of the equation.
-5 + 5 + 3x2 = 70 + 5
Combine like terms: -5 + 5 = 0
0 + 3x2 = 70 + 5
3x2 = 70 + 5
Combine like terms: 70 + 5 = 75
3x2 = 75
Divide each side by '3'.
x2 = 25
Simplifying
x2 = 25
Take the square root of each side:
x = {-5, 5} and that’s it.
