Question

Solving equation with quadratic formula.

Question will be given below

Answer 1

\[\large 2x^2 - 5x = 52\]

Answer 2

I know that the quadratic formula is:
\[\large x = \frac{ -b \pm \sqrt{b^2 - 2ac} }{ 2a }\]

Answer 3

a quadratic equation of the form:

ax^2 + bx + c = 0

has roots defined by the quadratic formula as:

\[x=\frac{1}{2a}(-b\pm\sqrt{b^2-4ac})\]
which is just a shortcut of completing the square

Answer 4

\[\large x = \frac{ -(-5) \pm \sqrt{(-5)^2 - 2(2)(-52)} }{ 2(2) }\]

if i solve it like this will it be fine?

Answer 5

Answer 6

might be a typo, but its 4ac, not 2ac

Answer 7

otherwise your values for abc are good

Answer 8

ok

Answer 9

\[x = \frac{ 5 \pm \sqrt {25 + 208} }{ 4 }\]

Answer 10

if solve it with this will it be correct? @amistre64
