We know that x²+px−35=0-------> <span>has one root that is equal to 7 so substitute x=7 in the equation </span>7²+p*7−35=0 49+p*7−35=0 14+p*7=0 p=-14/7------> p=-2
the answer Part a) is t<span>he value of the coefficient p is -2 </span> Part b) <span>Find the other root </span>x²+px−35=0-----> x²-2x−35=0 <span> using a graph tool-------> to resolve the second order equation see the attached figure
the other root is x=-5
the answer part b) is </span> the value of the other root is -5<span>
