Answer:
x = -1
Step-by-step explanation:
The x value of the axis of symmetry is precisely halfway between the two given x-intercepts: -5 and 3 are 8 units apart. Add half of 8 units, or 4 units, to -5, to obtain:
-5 + 4 = -1
The equation of the axis of symmetry is therefore x = -1.

Step-by-step explanation:
Answer: 4x²-9
Step-by-step explanation:
Step 1 : Equation at the end of step 1 : 22x2 - 9.
Step 2 : Trying to factor as a Difference of Squares : 2.1 Factoring: 4x2-9. Check : 4 is the square of 2. Check : 9 is the square of 3. Check : x2 is the square of x1 Factorization is : (2x + 3) • (2x - 3)
