5x^2-10x+28=3+20x-4x^2
simplify, using radicals as needed. express complex numbers in terms of i.

Answer 1

Add like terms.

Answer 2

9 x^2-30 x+25 = 0

Answer 3

x = 5/3

Answer 4

\[\large 5x^2-10x+28=3+20x-4x^2\]



\[\large 5x^2-10x+28-3-20x+4x^2=0\]



\[\large 9x^2-30x+25=0\]



\[\large (3x-5)^2=0\]



\[\large 3x-5=\sqrt{0}\]



\[\large 3x-5=0\]



\[\large 3x=5\]



\[\large x=\frac{5}{3}\]
