Factour ouf 3
f(x)=3(x²-9)
recognize diference of 2 perfect squres
a²-b²=(a+b)(a-b)
x²-9=x²-3²=(x+3)(x-3)
so
f(x)=3(x+3)(x-3)
seto to zero to find roots
0=3(x+3)(x-3)
0=x+3
-3=x
0=x-3
3=x
roots at x=-3 and 3
Answer:
Question 9: 35 Question 10: 10
Step-by-step explanation:
Use BEDMAS (Brackets Exponents Division Multiplication Addition Subtraction).
Question 9:
Start with the brackets.
10 x 4 - (7 - 2)
= 10 x 4 - (5)
Then, multiply 10 and 4.
= 40 - 5
Solve the subtraction.
= 35
Question 10:
Start with the brackets.
1 - (2 - 3) + 8
= 1 - (-1) + 8
= 1 - - 1 + 8
(Two negatives = a positive)
= 1 + 1 + 8
Add the numbers.
= 10
