Answer:x=1x=1 and x=−6x=−6Explanation1. Identify the coefficients from the equation x2+5x−6x2+5x−6. Here, a=1a=1, b=5b=5, and c=−6c=−62. Use the quadratic formula x=−b±D2ax=2a−b±D where D=b2−4acD=b2−4ac3. CalculateD=52−4(1)(−6)=25+24=49D=52−4(1)(−6)=25+24=494. Find the roots: x=−5±492(1)x=2(1)−5±495. Calculate x=−5±72x=2−5±76 .The solutions are x=1x=1 and x=−6x=−6by-step explanation:
