but this is +3, where is the 3? the only way to get the 3 is 5-8
sorry 8-5
Oops, my bad! Let me rewrite.
I believe this is a quadratic formula problem but the inside of the square root gave me
Find the product of the solution of this equation
|dw:1354209002036:dw|
|dw:1354209128299:dw|
\[5x^2+3x+8=0\]
Sorry, I was not paying attention in my deleted response (see how easy it is to go too quickly and get it wrong?!). @mew55 is correct...you do need the quadratic formula: \[x = \frac{-b \pm \sqrt{b^{2} - 4ac}}{2a} = \frac{-3 \pm \sqrt{3^{2} - 4(5)(8)}}{2(5)} = \frac{-3 \pm \sqrt{9 - 160}}{10} = \frac{-3 \pm \sqrt{151}}{10}\] 151 is a prime number, so you can't simplify any more than that without a calculator.
does the 'i' needs to be simplify since the inside of the square root is -151?
and its okay XD
Forgot the negative in the final square root...should be: \[\frac{-3 \pm \sqrt{-151}}{10}\]
@mew55...you could: \[\frac{-3 \pm \sqrt{151}(i)}{10}\]
yep. that is wut i was thinking. XD X3
