Step-by-step explanation:
x³ - 4x² + 3x
= x(x² - 4x + 3)
= x(x -3)(x - 1)
× = 0, 1, 3
Answer:
B
Step-by-step explanation:
Firstly the unfilled circle means that it is not equal to
If you read the scale the unfilled circle is at -1 and the arrow is pointing left.
This means that x is smaller than -1 or -1 is greater than x read in the form x<-1
The filled circle means x can be equal to, in this case, 4. The arrow is pointing right so x is greater or equal to 4
x≥4
Therefore the answer is b

Step by step solution :Step 1 : 3 - a Simplify ————— 21 Equation at the end of step 1 : (a - 3) (3 - a) ——————— ÷ ——————— 7 21 Step 2 : a - 3 Simplify ————— 7 Equation at the end of step 2 : (a - 3) (3 - a) ——————— ÷ ——————— 7 21 Step 3 : a-3 3-a Divide ——— by ——— 7 21
3.1 Dividing fractions
To divide fractions, write the divison as multiplication by the reciprocal of the divisor :
a - 3 3 - a a - 3 21 ————— ÷ ————— = ————— • ——————— 7 21 7 (3 - a)
3.2 Rewrite (3-a) as (-1) • (a-3) Canceling Out : 3.3 Cancel out (a-3) which now appears on both sides of the fraction line.
Final result : -3
