| Answer» USE the factor theorem: r is a root of polynomial p if and only if x−r is a factor of p. Since 7 is a solution of x3−67x+126=0, 7 is a root of x3−67x+126 so x−7 DIVIDES x3−67x+126. You may use polynomial LONG division to factor out x−7, leaving a quadratic polynomial that you can factor in standard ways.Step-by-step explanation:PLEASE mark as branlist | |
