Combine Logarithms: Combine the two logarithms using the product rule for logarithms, which states that logb(m)+logb(n)=logb(mn).log2((4x−3)(3x+5))
Expand Product: Expand the product (4x−3)(3x+5).4x×3x+4x×5−3×3x−3×512x2+20x−9x−15
Combine Like Terms: Combine like terms in the expanded expression. 12x2+11x−15
Write Single Logarithm: Write the combined expression as a single logarithm. log2(12x2+11x−15)
