4x2 + 3x is a quadratic polynomial. |
|
Answer» Answer: please follow me Step-by-step explanation: Given: α,β are zeroes of the polynomial 4x 2 +3x+7 To find the VALUE of α 1
+ β 1
We know that equation ax 2 +bx+c=0 Then sum of roots = a −b
and product of roots= a c
From the given quadratic equation, α+β=− 4 3
and αβ= 4 7
α 1
+ β 1
= αβ α+β
= 4 7
− 4 3
=− 7 3
⇒ α 1
+ β 1
=− 7 3
