by Quadratic formula ,
, values of x are
. None of mentioned options are correct according to question!
<u>Step-by-step explanation:</u>
Here we have , expression x2 + 20 = 2x or ,
.
We know that Quadratic formula is :


⇒ 

Putting this value in equation
:
⇒ 
⇒ 
⇒ 
⇒ 
⇒ 
Therefore , by Quadratic formula ,
, values of x are
. None of mentioned options are correct according to question!
Simplifying
3x + 4 = 7 + -2x
Reorder the terms:
4 + 3x = 7 + -2x
Solving
4 + 3x = 7 + -2x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '2x' to each side of the equation.
4 + 3x + 2x = 7 + -2x + 2x
Combine like terms: 3x + 2x = 5x
4 + 5x = 7 + -2x + 2x
Combine like terms: -2x + 2x = 0
4 + 5x = 7 + 0
4 + 5x = 7
Add '-4' to each side of the equation.
4 + -4 + 5x = 7 + -4
Combine like terms: 4 + -4 = 0
0 + 5x = 7 + -4
5x = 7 + -4
Combine like terms: 7 + -4 = 3
5x = 3
Divide each side by '5'.
x = 0.6
Answer: x = 0.6
