Answer:
6x+12
Step-by-step explanation:
This is an equivalent expression as all I did was simplify the expression using the distributive property. (6(x)) + (6(2)) = (6x) + (12) = 6x + 12
shown in reverse to prove this is equivalent would look like this. 6x+12 = (6(x)) + (6(2)) = 6(x+2)
Among the coefficient signs (++-) there is one sign change, so Descarte's rule of signs tells you there is one positive real root. Changing x to -x does not affect the signs, so there is also one negative real root. Then there are two complex roots to bring the total number to 4, the degree of the polynomial.
The factorization is
f(x) = (x^2 +25)(x^2 -4)
Each of these can be factored using the form for factoring the difference of squares.
f(x) = (x -5i)(x +5i)(x -2)(x +2)
There are 2 real roots: ±2.
There are 2 imaginary roots: ±5i.
Answer:
if there is a right angled square shape at the angle
Answer:
25/7=3.571428
Step-by-step explanation:
the mathematical expression of this equation is very simple that suggest that
25 must be divided by 7 which gives us the answer 3.571428....
this can be easily found by dividing 25 by 7 upto valid decimal digits.
