Question

Hey! :) I'll give metal!! And Fan! I just need to know how to do the next step...

Question asks to use the quadratic formula to solve the equation..

4x^2 - 6x - 10 = 0

So far I know that you can take the gcf of 2..

~2(2x^2 - 3x - 5)

Answer 1

if u can't find the answer, try using this formula :
\[x=\frac{ (-b)\pm \sqrt{b ^{2}-4ac} }{ 2a }\]

Answer 2

Im trying to factor this equation first.. Sorry I should have said something about that.

Answer 3

\[4x ^{2}-6x-10=0\] using that formula:
\[x=\frac{ 6\pm \sqrt{36+160} }{ 8 }\]
\[x=\frac{ 6\pm \sqrt{196} }{ 8 }\]
\[x=\frac{ 6\pm14 }{ 8 }\]
\[x=\frac{ 20 }{ 8 }=2,5\] or
\[x=\frac{ -8 }{ 8 }=1\]

Answer 4

Im not looking for what x.. lol
