Answer:
x^2 -6x + 222/25
Step-by-step explanation:
If the zeros are as above, then ;
x = 3-√3/5 or x = 3 + √3/5
Firstly, let’s represent √3/5 by b
Thus;
The two roots are ;
x = 3-b or x = 3 + b
so;
x+ b -3 and x -3-b
The quadratic equation is the product of the two
(x + b-3)(x - b -3)
x(x - b-3) + b(x -b -3) -3(x - b -3)
= x^2 -bx -3x + bx -b^2 -3b -3x + 3b + 9
Collect like terms and we are left with;
x^2 -6x -b^2 + 9
So let’s put back b = √3/5
x^2 -6x -(√3/5)^2 + 9
x^2 -6x -3/25 + 9
x^2 -6x + 222/25
Answer:
I hope this helps!
Step-by-step explanation:
3y(5x+3)=15yx+9y
2y(2x+3)=4yx+6y
4y(x+2)=4yx+8y
3y(7x+2)=21yx+6y
The answer is going to 25.13
In -2x
, the exponent will be dealt with first. With (-2x)
, the multiplication is going to be done first. This is determined because of Order of operations.
