Question

Solve 1 2 + 1 2x = x2 − 7x+10 4x

Answer 1

Answer:

$x_1=0.14\\x_2=-85.14$

Step-by-step explanation:

1. You have the following expression given in the problem above:

$12+12x=x^{2}-7x+104x$

2. Then, you need to add like terms, so you have:

$0=x^{2}+85x-12$

3. Apply the quadratic formula, as following:

$x=\frac{-b+/-\sqrt{x^{2}-4ac}}{2a}\\a=1\\b=85\\c=-12$

Then:

$x_1=0.14\\x_2=-85.14$
