The answer is: 83 + 12√35
(a + b)² = a² + 2ab + b²
In (2√5 + 3√7)², a = 2√5, b = 3√7
Just substitute a and b:
(a + b)² = a² + 2ab + b² = (2√5)² + 2 * 2√5 * 3√7 + (3√7)² =
= 2²√5² + 2 * 2 * 3 * √5 * √7 + 3²√7² =
= 4 * 5 + 12 * √(5*7) + 9 * 7 =
= 20 + 12 *√35 + 63 =
= 83 + 12√35
Answer:
ja s and the not only way I could
we know that
total of sum of arc is 360
so, sum of both arc must be 360
so, we get
now, we can solve for x
............Answer
H(X) = (x - 2)²(x + 4)(x - 1) has 3 zeroes, they are -4,2 and 1
Wait, this is simplified because there are no common terms.
