Q.1 If 1 is a zero of the polynomial p(x) = a_x2 – 3ax + 3a - 4, Find the value(s) of a.
​

Answer 1

Answer:

hello please follow me please mark as brainlist.

step by step

Since x+1 is a factor of the polynomial p(x)=x

2

−3ax+3a−7

Therefore, by Factor theorem p(−1)=0

⇒(−1)

2

−3a(−1)+3a−7=0

⇒1+3a+3a−7=0⇒a=1

Answer 2

Answer:

a =1

this is answer .................
