Solve for x in the equation 2 x squared + 3 x minus 7 = x squared + 5 x + 39.
x = negative 6 plus-or-minus startroot 82 endroot
x = negative 6 plus-or-minus 2 startroot 17 endroot
x = 1 plus-or-minus startroot 33 endroot
x = 1 plus-or-minus startroot 47 endroot

Step-by-step explanation:

We want to solve for x in

You need to group and combine like terms and write in standard form:

By comparing to , we a=1,b=-2 and c=-46

The solution can be obtained using the quadratic formula.

We substitute the coefficients to get:

The last choice is correct

hi,

i'm 75% sure the answer is 1,1 to both lines.

have a great day
