Factor each quadratic equation: 8x^2+10x-3 25x^2+10x-3 9x^2-15x-14 12x^2+17x-5 I don't get how to even start these! Help!

Graph it out and use the Pythagorean theorem to find 2 sides. Multiply those together.

I got the third one (3x-7)(3x+2) but I can't figure out the 4th one. How do I do this that one? I know it can only be 5 and 1, but I tried all of the x values and it doesn't work! I tried 6 and 2, 12 and 1, and 4 and 3

Wait I got it! (3x+5)(4x-1). I have a few more...

2x(3x+4)-3(3x+4) -2x(x+7)-(x+7)

Ya I figured those out, but I put down your equation into my notes cause it made more sense than what I did. How do I factor with -x?

Ya, but one is x^2=14x+5

Oh! I get that now! Thank u soo much!
