Question

find the value of 'a' fornwhich (x-1) is a factor of the polynomial a²x³-4ax+4a-1​

Answer 1

HEY MATE HERE'S YOUR ANSWER.....;

IF (X-1) IF FACTOR OF POLYNOMIAL

THEN,

X= 1 IS SOLUTION OF POLYNOMIAL

SO,

$a {}^{2} (1) {}^{3} - 4a(1) + 4a - 1 = 0$

$a {}^{2} - 4a + 4a - 1= 0$

$a \: = \sqrt{1 }$

$a = 1$

HOPE IT'S HELPFUL......:-)
