Answer: c
hope this helps you out & i’m not 100% sure if this is right so sorry if u get it wrong .
First off, remember that finding the x-intercepts means setting y equal to zero and solving for the x-values, so this question is really asking you to "Solve 4x2 – 2x – 5 = 0".
Now, let's start the completing-the-square process. To begin, we have the original equation (or, if we had to solve first for "= 0", the "equals zero" form of the equation). In this case, we were asked for the x-intercepts of a quadratic function, which meant that we set the function equal to zero
Answer:
The answer is -575°,−215°,505°,865°
I don't know what you mean by factors, but the quadratic equation of m^2 - 12m + 20 can be simplified to (m - 10)(m - 2).
Hope this helps!
Use the formula d=sqrt[(x_2-x_1)^2+(y_2-y_1)^2]
