Question

if one root of the equation (x+4)(x-3)=0 is 1-4 then find the other root​

Answer 1

Step-by-step explanation:

Correct option is

C

3

1 is the root of the given quadratic equation. Thus,

(1)

2

+p(1)+3=0

p+4=0

p=−4

Thus, the equation becomes x

2

−4x+3=0

x

2

−x−3x+3=0

x(x−1)−3(x−1)=0

(x−1)(x−3)=0

x=1,3

Hence, the other root of the equation is 3.
