Answer:

x_1=1\\x_2=\frac{1}{2} =0.5

Step-by-step explanation:

Given a equation of the form:

ax^2+bx+c=0

The roots of this equation can be found using the quadratic formula which is given by:

x=\frac{-b\pm\sqrt{b^{2}-4ac } }{2a}

In this case we have this equation:

2x^2-3x+1=0

So:

a=2\\b=-3\\c=1

Using the the quadratic equation :

x= \frac{-(-3)\pm\sqrt{(-3)^{2}-4(2)(1) } }{2(2)} = \frac{3\pm\sqrt{9-8 } }{4}=\frac{3\pm 1}{4}

Therefore the two roots would be:

x_1=\frac{3+ 1}{4}=\frac{4}{4}= 1\\x_2=\frac{3- 1}{4}=\frac{2}{4}=\frac{1}{2}=0.5

Answer:

Sample Response: First, the like terms had to be combined using the lowest common denominator (LCD). Then the subtraction property of equality was used to isolate the variable term. Finally, both sides of the equation were multiplied by the reciprocal of the coefficient to solve for a.
