<p>yes...but this pop up with i type in -2 and 5</p>
<p>ERR: NO SIGN CHNG
1: Quit
2: GOto</p>
<p>which equation are you typing in, kelqu?</p>
<p>x^2+x-1-(3x-4)</p>
<p>x^2+x-1-(3x-4)</p>
<p>is the same as </p>
<p>x^2-2x+3</p>
<p>b^2-4ac = 4-12 = -8 .. since b^2-4ac is negative, there is no solution. that's why an error msg popped up ...
sorry to give you a bad example ... try</p>
<p>x^2+3x-9</p>
<p>When I type 3x^2-2x+5 in equation solver, I get an error. Did I do something wrong? And how can you solve for the cube root of 8 in the calculator?</p>
<p>nope .. that's right .... b^2-4ac would be 4-4(3)(5) .. and since that's negative there is no solution </p>
<p>to get the cube root of 8 .. you could do it two ways
taking the cube root of a number is the same as raising it to the one third .. so you could type 8^(1/3)
you could also go into the math menu and there will be a button that has a 3 by the root (hence cube root) .. hit that and then type in 8. (notice the one with star can be ANY root ... so you type in 4 before-hand if u want 4th root)</p>
<p>Can someone send me this program. Thanks.</p>
<p>for solving equations like 3x^2 + 5x=logx + sinx or something crazy like that instead of getting everything onto one side and using equation solver u can put the left side of the equation into Y1 and the right side of the equation into Y2 and graph these two equations and find where they intersect. the calculator will find the exact intersection point for u if u hit 2nd trace and go down to intersect. i have found that this saves me a TON of time</p>
<p>Can someone send me this program too! I really need it. </p>
<p>Thanks so much!</p>
<p>Where can I find this ■■■■■■ program?</p>
<p>I didn’t study at all going into the ACT (I focused more on SAT), but I got a 35 on the math portion. It’s really simple math- mainly algebra and geometry.
I remember a lot of tricks from geometry, which helped me.</p>
<p>I know for a fact that the ACT has alot of geometric/linear sequences…</p>
