We have
(a + b)² = a² + 2ab + b²
so that with a = x² and b = 5, we have
x⁴ + 10x² + 25 = (x² + 5)²
Next, we have
a² - b² = (a - b) (a + b)
so that with a = x and b = √5 i,
x² + 5 = x² - (-5) = (x - √5 i) (x + √5 i)
So, the complete factorization over the complexes is
(x - √5 i)² (x + √5 i)²
First, realize that angle ABC is the sum of the two other angles. Hence, form an equation in which you subtract the measure of one of the angles from angle ABC to get the measure of the other angle -- the one you are solving for.
Answer:
No. it would be 4 3/14
Step-by-step explanation:
5-1=4
common denominator is 14 to get there,
1x7=7
2x7=14
2x2=4
7x2=14
7/14 - 4/14 = 3/14
put it all back together and you get 4 3/14
