Cristiano Ronaldo has 45 fewer goals on record than Josef Bican. Write an expression to represent the number of goals Cristiano Ronaldo currently has if Josef Bican had G goals.

How many goals does Ronaldo have if Josef Bican has a record of 805 goals?

Correct A

Explanation:

A. Given that the equation x2+ mx+ n= 0 has two solutions, x = kand x = 2k,you can work backward to build the original equation. Here’s how:

x= kx= 2k

x– k= 0 x– 2k= 0

Now take the two equations and combine them:

(x– k)(x– 2k) = 0

x2– 2kx– kx + 2k2= 0

x2– 3kx + 2k2= 0

As you can see, m= –3kand n = 2k2, so mn= –6k3.

the simplified form is

step-by-step explanation:

we want to simplify the expression,

let us change the middle bar to a normal division sign to obtain,

we multiply the first fraction by the reciprocal of the second fraction to obtain,

we factor to obtain,

we cancel the common factors to get,

we simplify to get,

the correct answer is b
