gxg=g^2
gx2=2g
7xg=7g
7x2=14
g^2-2g-7g+14 then simplify g^2-9g+14 is the answer
Answer:
3(x - 5)(x + 1).
Step-by-step explanation:
3x^2 - 12x - 15
Dividing through by 3:
= 3(x^2 - 4x - 5)
We need 2 numbers whose sum is -4 and whose product = -5. That is -5 and +1 , so the factors are:
3(x - 5)(x + 1).
Answer:
22/24
Step-by-step explanation:
To figure this out, both the numerator and the denominator of the equivalent fraction have to be proportional to 11/12.
To do that, multiply the numerator (11) by 2, (because the denominator of the second fraction is 2 times the denominator of the first fraction).
The second, proportional fraction is 22/24.

<u>Biquadratic Equations</u>
Solve:

The biquadratic equations are equations of degree 4 without the terms of degree 1 and 3.
Solving such equations requires to express the equation as a second-degree equation with
as the variable.
Rewriting the equation:

The quadratic equation can be factored as:

It leads to two equations:


The first equation has imaginary roots. Solving for x:




Where

The second equation has two real roots:





The roots are:
