Question

2x3-13x2+26x-15 divided by x-1​

Answer 1

Answer:

Remainder=0

step by step explanation:

• x-1. (given)
• x=1
• 2 x³ -13x² +26x -15 .....(1) (given)
• put x=1 in eqn . (1)
• 2(1)³ -13(1)² +26(1) -15
• 2-13+26-15
• -11+11=0

Answer 2

Answer:

method 1: remainder theorem

2x³-13x²+26x-15

x-1=0. x=1

2*1³-13*1²+26*1-15

2-13+26-15

26+2-13-15

28-28

remainder =0
