Answer 1

if the ques is x² + 13x² + 31x - 46 then it wud b impossible to solve it so the correct ques will b x² + 13x² + 31x - 45...now to solve it ::

let f(x) = x²+13x² +31x-45

let x = 1

f(1) = 1+13+31-45 = 0

•°• x-1=0

now , x-1 ) 14x² + 31x -45 ( pls c the division on the attachment

hope i am of some help
