Chase solved the quadratic equation x2 + 10x - 5 = 0 using the quadratic formula. Finish solving for x. What are the solutions in simple radical form.

B

Step-by-step explanation:

= · = 2

[(-10 ± ) / 2] which simplifies to be (-10 ± 2)/2

[(-10 ± 2)/2] can be simplified to be -5 ±

answer: option a.

step-by-step explanation:

you know that the quadrilateral opqr ( a four sided figure) is inscribed in circle. this means that all its vertices are on the circle.

then, by definition, the opposite angles of the quadrilateral are supplementary, this means that the sum of their measures is 180 degrees.

you can observe in the figure that the angles ∠opq   and the angle ∠orq   are opposite, therefore:

then, can be used to d to calculate the measure of ∠opq
