Chech wether 7+3x is a factor of 3xcube+7x |
|
Answer» HEY If 7x +3 is a FACTOR of the given POLYNOMIAL then it must be giving ZERO if we put -7/3 as the value of x. 3(-7/3)³ + 7(-7/3) -343/9 - 49/3 =-343-147/9 -490/9 This is not coming zero, therefore it's not a factor of the given polynomial. HOPE it helps :)) |
