Question

71) The equation x² + 5x - 6=0 has roots panda, also the equation 3x + ax + b =0 has roots p+2 and q +2. What is the value of a +b? ​

Answer 1

Answer:

for the equation

${x}^{2} + 5x - 6 = 0$

roots are 1,-6

Step-by-step explanation:

let p= -6 and q=1 then p+2= -4 and q=3

sum of these roots = -1

product of these roots = -12

in the given second equation

we have, sum= - b/a = -a/3= -1

after solving we get a=3

product = c/a = b/3= -12

we'll get b= -36

hope I'm clear

thank you
