Question

Solve this quadratic equation using the quadratic formula. 2x^2 - 10x + 7 = 0

Answer 1

x=5 (+-) sqr root 11 / 2

Explanation:

Answer 2

The quadratic formula is (-b+-sqrt(b^2-4ac))/(2a)
In your equation,
A=2
B=-10
C=7
Plugging these in we get
(10+-sqrt(100-4(2)(7)))/(2*2)
=(10+-sqrt(44))/4
=(10+-6.633)/4
=16.633/4 or -3.366/4
=4.158 or -0.841

Final Answer:
x=4.158 or x=-0.841
