The denominator : q² - 3q - 4 should be ≠ 0.
Let's find the zero values of this quadratic equation:
q' = [-b+√(b²-4.a.c)]/2.a and q'' = [-b-√(b<span>²-4.a.c)]/2.a
you will fond q' = 4 and q'' = -1
Then the restrictions are :
q </span>≠ 4 and q ≠ - 1 (1st answer)
Answer:
-15x-4
Step-by-step explanation:
-21x + 6x-4
-15x-4
It would be 10
You substitute “x”for “3” so the equation would be 2(3) + 4. Then you multiply 2 and 3, which is 6. Finally add the 4 to get 10.
