Hope i understand it right
9y^2 -12y^4 = 3y^2 *(3 - 4y^2)
Mrs. Harper drove 102 miles and Mr. Harper drove 408. Am I right?
The answer would be 2.5.
hope this helps (;
9 servings, 5×3=15 but for each 5 equals 3 so,3 +3+3 =9 because 5 is a serving
y= -4x² - 16x - 14
Take the coefficient of x² as the common factor
y = - 4(x² + 4x + 7/2)
Add (b/2)² to complete the square
y = - 4( x² + 4x + 2² - 2² + 7/2)
Complete the square
y = -4( (x + 2)² - 1/2)
Remove the bracket
y = -4(x + 2)² + 2
Answer: y = -4(x + 2)² + 2
