QuestionFind the missing factor DD in the equation 15y4=(D)(3y2)-15 y^{4}=(D)(3 y^{2}).

Studdy Solution

STEP 1

Assumptions1. The equation given is 15y4=()(3y)-15 y^{4}=()\left(3 y^{}\right). We are looking for the missing factor $$

STEP 2

We can start by isolating $$ on one side of the equation. We can do this by dividing both sides of the equation by $y^2$.
=15y4y2 = \frac{-15 y^{4}}{ y^{2}}

STEP 3

Now, simplify the right side of the equation by dividing 15-15 by 33 and y^ by y2y^2.
=153yy2 = \frac{-15}{3} \cdot \frac{y^{}}{y^{2}}

STEP 4

Calculate the division of 15-15 by 33 and simplify the power of yy by subtracting the exponents.
=y42 = - \cdot y^{4-2}

STEP 5

Calculate the subtraction of the exponents.
=5y2 = -5 \cdot y^{2}So, the missing factor $$ is $-5y^2$.
