Step-by-step explanation:
2x^2-10x+7 A=1, B=-10. C=7
-(-10)±√-10^2-4(1)(7)

<u>10+8.485281374 </u>=9.24

<u>10-8.485281374</u> =0.76

We have that
(v+6)^2 = 324-----> I raise to 1/2 both members----> [(v+6)^2]^(1/2)=(324)^(1/2)[(v+6)]=(324)^(1/2)-------------> v+6=√324
v=√324-6---------> 18-6=12
v=12
the answer is v=12
Answer:
175
