Answer:
12-4u
Step-by-step explanation:
Hope i understand it right
9y^2 -12y^4 = 3y^2 *(3 - 4y^2)
When you have to divide by a fraction, you have to multiply the other number by the fraction's reciprocal.
8 = 3/4 w Divide by 3/4
w = 8/(3/4)
w = 8/ (3/4) = 8 x 4/3 Multiply by the numerator and divide by the denominator.
w = (8 x 4) / 3
w = 32 / 3
w = 10 2/3
