Question

(4y+8)(1,8-2y)=0 срочно

Answer 1

Ответ:

(4y+6)(1.8-0.2y)=0

7.2y-0.8y²+10.8-1.2y=0

-0.8y²+6y+10.8=0

D=36-4*(-0.8)*10.8=70.56

y1=(-6+8.4)/(-1.6)=-1.5

y2=(-6-8.4)/(-1.6)=9

Answer 2

To solve the equation (4y+8)(1.8-2y) = 0, we can use the zero product property. According to this property, if the product of two factors is equal to zero, then at least one of the factors must be equal to zero.

So, we can set each factor equal to zero and solve for y.

Setting 4y+8 = 0: 4y = -8 y = -8/4 y = -2

Setting 1.8-2y = 0: -2y = -1.8 y = -1.8/-2 y = 0.9

Therefore, the solutions to the equation (4y+8)(1.8-2y) = 0 are y = -2 and y = 0.9.
