Answer: x=−1/2,4/3Step-by-step explanation:1. Split the second term in 6x^2−5x−4 into two terms.6x^2+3x−8x−4=02. Factor out common terms in the first two terms, then in the last two terms.3x(2x+1)−4(2x+1)=03. Factor out the common term 2x+1.(2x+1)(3x−4)=04. Solve for x.Ask: When will (2x+1)(3x−4) equal zero?When 2x+1=0 or 3x-4=0Solve each of the 2 equations above.x=−1/2,4/3
