Question

using the quadratic formula solve each equation. give two forms of each solution an expressionwith radical and a calculator approximation rounded off to two decimal places.   2x^2+3x-4=0. I am a bit confused what the quadratic farmula is. Can anyone help.

$$quadratic formula = -b \left( +or- \right)*(\sqrt{b ^{2}-4ac})/2a$$

anonymous · Answer

there is a song: negative b, plus or minus square root, b squared minus 4 a c, all over 2 a. kinda lame but good to memorize, just say each section twice ^^

That is cool

anonymous · Answer

so how do I use this to solve my question?

anonymous · Answer

2x^2 +3x -4 = 0
a = 2
b = 3
c = -4
you just use the coefficients of the numbers

ok
