Question

If (x - 2a) is a factor of 2x4

- 4ax3 + 7x2

- 13ax - 18, find the value of a.​

Answer 1

Step-by-step explanation:

f(x)= 2x⁴-4ax³+7x²-13ax-18

here x-2a is a factor so x=2a will be satisfy this equation

so. put x=2a

f(2a)=0

2(2a)⁴-4a(2a)³+7(2a)²+13a(2a)-18=0

2(16a⁴)-4a(8a³)+7(4a²)+126a²18=0

32a⁴-32a⁴+28a²-26a²-18=0

2a²-18=0

2a²=18

a²=9

a=±3
