Can anyone please help me to solve these add math questions?
1) It's given that 3 and m+4 are the roots of the quadratic equation x^2 +(n-1)x +6=0,
Where m and n are constants. Find the value of m and n .
2) A quadratic equation x^2 +4(3x+k)=0 , where k is a constant has roots p and 2p , p is not equal to 0.
- Find the value of p and k.
-hence form the quadratic equation which has roots p-1 and p+6.
Pls help me and show out your steps . Thanks
