Sagot :
8x^2 - 2x -7
2(+/-) the square root of (4-224), all divided by 16
- simplified form is 1 (+/-) 2i times the square root of 55, all divided by 8
2(+/-) the square root of (4-224), all divided by 16
- simplified form is 1 (+/-) 2i times the square root of 55, all divided by 8
8x^2 - 2x -7 = 0 Subtract 7 on both sides in order to get 0
Quadratic Formula: -b +/- radical(b^2 - 4ac)
-----------------------------
2a
So, inputting the numbers from the equation, you would get:
1.
2 +/- radical(-2^2 - 4(8)(-7))
---------------------------------
2(8)
2.
2 +/- radical(4 +224)
-----------------------
16
3.
2 +/- radical(228)
--------------------
16
4.
2 + radical(228) 1 radical(228)
------------------- => --- + ------------
16 8 16
2 - radical(228) 1 radical(228)
------------------ => --- - -------------
16 8 16
If you chose to, you could simplify radical(228)
