I need help with this Factoring Quadratics question.Can someone help me?
antoniya [11.8K]

If you mean "factor over the rational numbers", then this cannot be factored.

Here's why:

The given expression is in the form ax^2+bx+c. We have

a = 3

b = 19

c = 15

Computing the discriminant gives us

d = b^2 - 4ac

d = 19^2 - 4*3*15

d = 181

Note how this discriminant d value is not a perfect square

This directly leads to the original expression not factorable

We can say that the quadratic is prime

If you were to use the quadratic formula, then you should find that the equation 3x^2+19x+15 = 0 leads to two different roots such that each root is not a rational number. This is another path to show that the original quadratic cannot be factored over the rational numbers.

Three cartons of juice cost $4.77? find the cost of 8 cartons
AleksAgata [21]
Note: <span>Make the rule of three simple

cartoons __ price $
3 --------------- 4.77
8 --------------- y

Solving: (</span><span>directly proportional)
</span>
\frac{3}{8} = \frac{4.77}{y}
<span>Product of extremes equals product of means
</span>3*y = 8*4.77
3y = 38.16
y =  \frac{38.16}{3}
\boxed{\boxed{y = 12.72}}\end{array}}\qquad\quad\checkmark

If its 2 dollar per book and they need 300 dollar, you need to divide 300 by 2 which is 150 students. you will need 150 students for each to pay 2 dollars. just to be sure, 150 students times 2 dollar is 300 dollars
