Answer:
x = -2, -5 where -2 is a double root
Step-by-step explanation:
The real roots are the solutions to the cubic equation. You find them by setting each factor equal to 0 and solving for x.
Since -2 appears twice, it is a double root.
After distributing you get this equation. 2r+4 =2r+4 since it's the same expression on both sides the answer would be r=All real numbers because no matter whatever real number u put for r it will come out the same on both sides
Answer:
Sorry
Step-by-step explanation:
But no
Q=5*x^2+3*(8-x)^2
dq/dx=10x-6(8-x)=16x-48....1
To minimise q dq/dx=0......2
x=3 and y=5 on solving 1&2
= 9k-5k+9x-5x-15-26
= 4k+9x-5x-15-26
= 4k+4x-15-26
= 4k+4x-41
Hope this helps! Good luck!
