What is the value of ax² + bx + c, if x =
-b |
a |
Answer:
c
- Here we have to find the value of ax² + bx + c, where the value of x is
.-b a - Let us place the value of x in ax² + bx + c.
= a(
)² + b(-b a
) + c-b a
= a ×
+ b × (b² a²
) +c-b a
=
-b² a
+ cb² a
= c - Thus, the value of ax² + bx + c is c.
