Question

Px) ax2 + bx +



c. If a + b +c 0, then find one of its zero.

Answer 1

1. Question⇒  P(x)=ax2+bx+c. if a+b+c=0 then find one of its zero

Step-by-step explanation:

• P(x ) = ax² + bx + c  
• put x = 1  
• P(1) = a + b + c  
• but a + b + c = 0
• so, P(1) = 0  
• so, x = 1 is the root of P(x )
