Answer: the equation is
4x^2 + 4x - 12
Step-by-step explanation:
A quadratic equation is an equation in which the highest power of the unknown is 2.
The general form of a quadratic equation is expressed as
ax^2 + bx + c
Where
a is the leading coefficient
c is a constant
Assuming we want to write the quadratic equation in x, from the information given, the roots which are given are -2 and 1 and the leading coefficient is 4.
Therefore, the linear factors of the quadratic equation will be (x+2) and (x-1)
the equation becomes
(x+2)(x-1)
= x^2 - x +2x - 3
= x^2 + x - 3
Given a leading coefficient of 4, we will multiply the quadratic expression by 4. It becomes
4(x^2 + x - 3)
= 4x^2 + 4x - 12

Answer:
$20.58
Step-by-step explanation:
28 x 0.30 = 8.4
28 - 8.4 = 19.6
19.6 x 0.05 = 0.98
19.6 + 0.98 = 20.58
If it takes a ball to roll 12 meters per sec, and asks how far it will roll for 3 seconds you would multiply 12 and 3 getting 36.
The ball will roll 36 meters for 3 seconds
