Plz fast solve for x in the equation 2 x squared minus 5 x + 1 = 3. x = five-halves plus-or-minus startfraction startroot 29 endroot over 2 endfraction x = five-halves plus-or-minus startfraction startroot 41 endroot over 4 endfraction x = five-fourths plus-or-minus startfraction startroot 29 endroot over 2 endfraction x = five-fourths plus-or-minus startfraction startroot 41 endroot over 4 endfraction

Step-by-step explanation:

We re-write the equation subtracting from both sides 3, so as to get a quadratic expression equal to zero and be able to use the quadratic formula to solve it:

Now we use the quadratic formula considering that

answer: need picture of problem

step-by-step explanation:

answer:

it is general formula that is used to write value to its excet position

a11 a12 a13

a21 a22 a23

it is the example of order 2 by 3 matrix in this

a11 means value occur in 1 st row 1st column

a12 means value occurs in 1st row 2nd column

a13 means value occur in 1st row and 3rd column

a21 means value occurs in 2nd row and 1st column

a22 means value occurs in 2nd row and in 2nd column

a23 means value occurs in 2nd row and in 3rd column
