Given:
The quadratic equation is

To find:
The x-intercepts of the given equation.
Solution:
We have,

Splitting the middle term, we get



For x-intercepts, y=0.

Using zero product property, we get




So, the x-intercepts are (0.5,0) and (2,0).
Therefore, the correct option is a.
Sum= 348. you didn't have to regroup because no number went over 10
