Question

Factorise: 3x^2 + 5x -3

Answer 1

Hello, Clover,
Tried factoring 3x^2 + 5x -3 using synthetic division. No soap.
Next, I applied the Quadratic Formula and obtained two complex results. Have you tried that? Once you have those roots, you can write the factors.

More info for you after I've heard back from you.

Answer 2

I don't really understand...

Answer 3

I'll need for you to share with me what you DO understand about factoring quadratics.

Answer 4

Sum and product

Answer 5

I have tried repeatedly to obtain the roots of your expression, and have found two roots by graphing this function on my calculator. But these roots are not integers; they're fractions. Would you mind double-checking to ensure that the actual original expression

3x^2 + 5x - 3? Thank you.

Answer 6

Yes, it's definitely that, I've got a work sheet that my teacher gave me.

Answer 7

Hold this problem. Circle it. Post the next problem on your worksheet, please.

Answer 8

The function you have posted here can be factored approximately, but not exactly. I did this by plotting it, finding the numeric roots using my calculator (they are approx. x=-2.135 and x=0.4684). Therefore, one factor is approx. (x+2.135) and the other (x-0.4684).

I'd suggest you check with your teacher regarding this problem. Ask whether you and I (your helper) are overlooking something.

Answer 9

Okay! Thank you anyway!
