Answer:

x=√414

Step-by-step explanation:

2x2−5x+1=3

aaaaaaa−3a−3aaaSubtract 3 from both sides

2x2−5x−2=0

This equation is not factorable, so use the quadratic formula.

x=−b±b2−4ac2aaaa foraaaax2+bx+c=0

a=2,b=−5,c=−2

x=(−5)±(−5)2−4(2)(−2)2⋅2

x=√414

hope this helped :)

Answer:


x=(5\pm√(41))/(4)

Step-by-step explanation:

We have been given an equation
2x^2-5x+1=3. We are asked to solve for x.

First of all, we will convert our given equation in standard form of equation as:


2x^2-5x+1-3=3-3


2x^2-5x-2=0

Now, we will use quadratic formula to solve for x.


x=(-b\pm√(b^2-4ac))/(2a)


x=(-(-5)\pm√((-5)^2-4(2)(-2)))/(2(2))


x=(5\pm√(25+16))/(4)


x=(5\pm√(41))/(4)

Therefore, the solutions for our given equation are
x=(5\pm√(41))/(4).
