Step-by-step explanation:
x-3=0
x-3=0x=3
x-3=0x=3substitute x=3 value in 3x³-5x²-11x-3
x-3=0x=3substitute x=3 value in 3x³-5x²-11x-3= 3(3)³-5(3)²-11(3)-3
x-3=0x=3substitute x=3 value in 3x³-5x²-11x-3= 3(3)³-5(3)²-11(3)-3= 3(27)-5(9)-33-3
x-3=0x=3substitute x=3 value in 3x³-5x²-11x-3= 3(3)³-5(3)²-11(3)-3= 3(27)-5(9)-33-3= 81-45-33-3
x-3=0x=3substitute x=3 value in 3x³-5x²-11x-3= 3(3)³-5(3)²-11(3)-3= 3(27)-5(9)-33-3= 81-45-33-3= 81-81
x-3=0x=3substitute x=3 value in 3x³-5x²-11x-3= 3(3)³-5(3)²-11(3)-3= 3(27)-5(9)-33-3= 81-45-33-3= 81-81= 0
x-3=0x=3substitute x=3 value in 3x³-5x²-11x-3= 3(3)³-5(3)²-11(3)-3= 3(27)-5(9)-33-3= 81-45-33-3= 81-81= 0 Hence Verified
