Question

pls say the answer if you know the answer​

Answer 1

Answer:

Step-by-step explanation:Let 4u² + 8u = 0

4u(u + 2) = 0

4u = 0 or u + 2 = 0

u = 0 or u = -2

sum of the roots = -b/a  = -8/4 = -2

But sum of the roots = 0 + (-2) = -2

Product of the roots = c/a = 0 (As there is no c in the equation)

But, product of the roots = 0 × –2 = 0

Answer 2

Step-by-step explanation:

x^2_2x_8

splitting of middle term

x^2_4x+2x_8

x(x_4)+2(x_4)

(x_4)(x+2)

x=4 or x=_2
