When you factor a quadratic ax² + bx + c, it becomes (x+m)(x+n), where mn = ac, and m+n = b.
In x²+x-6, we want to find two numbers that multiply to -6 and add to 1.
3 and -2 satisfy both of these criteria, so there are our factors.
In x²-7x+10, we want to find two numbers that multiply to 10 and add to -7.
-5 and -2 satisfy both of these criteria, so there are our factors.
The (x-2) cancels and we're left with
Answer: Simon needs 125ml of milk and craig needs 7.5g of butter.

The number of plants in each row is 5.
<h3>What are factors? </h3>
The factor of a number is a number that can be used to divide another number number evenly. For example, a factor of 20 is 2.
<h3>How many plants are in each row? </h3>
The number of plant in each row would be a factor of 15 that is between 4 and 8.
Factors of 15 = 1, 3, 5, 15.
