Question

if (x+1) is a factor of x2-3ax+3a-7 then the value of a is​

Answer 1

Step-by-step explanation:

(x+1) is a factor.

so x= -1

${x}^{2} - 3ax + 3a - 7 = 0 \\ ( { - 1)}^{2} - 3a( - 1) + 3a - 7 = 0 \\ 1 + 3a + 3a = 7 \\ 6a = 6 \\ a = 1$

Hence value of a is 1

KINDLY MARK AS BRAINLIEST...

Answer 2

mark me as brainliest

x=-1

p(x) =x*2-3ax+3a-7

p(-1)=(-1)*2-3a(-1)+3a-7

1+3a+3a-7=0

6a+1=7

6a=7-1

6a=6

a=6/6

a=1
