Q. Find the missing factor D that makes the equality true.−15y4=(D)(3y2)D=□
Identify Given Equation: Identify the given equation and what we need to find.We are given the equation −15y4=D×3y2 and we need to find the value of D.
Divide by 3y2: Divide both sides of the equation by 3y2 to solve for D.D=3y2−15y4
Simplify Right Side: Simplify the right side of the equation by canceling out common factors.D=(−15/3)×(y4/y2)D=−5×y4−2D=−5×y2
Check Result: Check the result to ensure there are no mathematical errors.−15y4=(−5×y2)×3y2−15y4=−5×3×y2×y2−15y4=−15y4The left side of the equation matches the right side, confirming that D=−5×y2 is correct.
