3p^2-2p-5 factor completely
fiasKO [112]
a x^{2} +bx+c Here is the basis equation. 3p ^{2} -2p-5 Let us use the AC method. Multiple the A and C values, or 3 and -5. This is -15. So now ask yourself... what multiplies to -15 but adds to -2. that would be, -5 and 3. So now reconstruct your equation ...(3p^2+3p)+(-5p-5) The larger number will go first (3>-5) Now you can factor each group. 3p(p+1)-5(p+1) Because what is now in the parentheses are qualm and they are being added, you can now make the coeffecients a group (3p-5) (p+1) If you are solving for p, set equal to zero and then the answers are -1 and (5/3). If you are just factoring, then that is your answer.
