Tip: Use the change of base formula to convert to base 10 (log) or base e (ln). Some calculators handle only these bases. 𝐥𝐨𝐠𝒃𝑴𝑵= 𝐥𝐨𝐠𝒃𝑴+ 𝐥𝐨𝐠𝒃𝑵 𝐥𝐨𝐠𝒃 𝑴 𝑵 = 𝐥𝐨𝐠𝒃𝑴−𝐥𝐨𝐠𝒃𝑵 LSC
Quadratic Formula To solve ax2 + bx+ c= 0, a6= 0, use : x= 2b p b 4ac 2a. The Discriminant The discriminant is the part of the quadratic equation under the radical, b2 4ac. We use the discriminant to determine the number of real solutions of ax2 + bx+ c= 0 as such : 1. If b2 4ac>0, there are two real solutions. 2. If b2 4ac= 0, there is one ...
