Question

if x+1 is a factor of square of x-3ax +3a-7

Answer 1

Your question needs a correction,

Correct question : find the value of a



By factor theorem, x = -1


x² - 3ax + 3a - 7 = 0

(-1)² - 3a(-1) + 3a - 7 = 0

1 + 3a + 3a - 7 = 0

6a - 6 = 0

6a = 6

$a = \frac{6}{6}$
a = 1




I hope this will help you

Answer 2

Heya!

Here is yr answer.....


Given,

=> x² -3ax + 3a -7

x+1 is the factor of the above eq.

x+1 = 0

x = -1



Now,

(-1)² -3a(-1) + 3a -7 = 0

1 + 3a + 3a - 7 = 0

6a - 6 = 0

6a = 6

a = 6/6

a = 1



Hope it hlpz..
