You must remember that a polynomial is written like so...
ax^2 + bx + c
In this case...
a = 1
b = 3
c = -10
To factor you must find two numbers who both add up to b (3) AND multiply to c (-10)
-2 + 5 = 3
-2 * 5 = -10
so...
(x - 2)(x + 5)
To find the zero you must set each factor equal to zero and solve for for x like so...
x - 2 = 0
x = 2
x + 5 = 0
x = -5
Hope this helped!

Answer:
Below is the step by step explaination of the procedure
Step-by-step explanation:
So since he wants to make three cakes we will multiply the recipe by 3 to get the amount of ingredients this person will need.
6*3 = 18 ounces of butter
5*3 = 15 ounces of sugar
7*3 = 21 ounces of flour
3*3 = 9 eggs
2 * 3 = 6 teaspoons of baking powder.
Answer:
The amount of water left is 1550 litres
Answer: 8
Step-by-step explanation:
We can use prime factor method , that is we will express each of the number as a product of their prime factor
64 = 2x2x2x2x2x2
72 = 2x2x2x3x3
Greatest common factor is therefore:
2 x 2 x 2= 8
The answer is <span>b. y=3x^2-5x+9
</span><span>
The general formula for quadratic function is:
y = ax</span>² + bx + c
Among all choices only b. is correct:
y = ax² + bx + c
y = 3x² - 5x + 9
