Answer: X= -9
Step-by-step explanation:
Multiply the 5 by x+4 then copy the -3x+3=5. It will be 5x+20-3x+3=5.
Then subtract or add the like terms
5x-3x and 20+3. It will be 2x+23=5
Then add -23 to both sides
It will be 2x+23-23=5-23 then solve it will be 2x=-18 then divide both sides by 2 to find the value of x
2x/2=-18/2 then the final answer is x= -9. I hope it help
Answer:
The answer is 3 and (-4).
Step-by-step explanation:
We are given an equation 2x² + 2x – 24.
Let us assume that the equation is equal to zero.
2x² + 2x – 24 = 0
Now, divide whole equation by 2 we get,
x² + x – 12 = 0
x² + 4x – 3x – 12 = 0
x(x + 4) – 3(x + 4) = 0
(x – 3) (x + 4) = 0
x = 3, -4
Thus, The actual roots of f(x) are 3 and (-4).
