Answer:
x=18
Step-by-step explanation:
y²+y²=(9√(2))²
2y²=81*2
y²=162/2
y²=81
y=9
hypotenuse: 2y=x 2*9=18
x=18
Answer:
There is another complex zero which is a conjugate of the known complex zero.
Explanation:
A quadratic equation s a 2nd order polynomial.
Therefore it can have 2 real zeros or 2 complex zeros.
Because complex zeros always occur as conjugate pairs, there will be another complex zero which is a conjugate of the known complex zero.
For example, if the known complex zero is of the form (a + ib), then the other complex zero is (a - ib), or vice versa.
Answer:
x = a
x = b
Step-by-step explanation:
solve the equation for x by finding a, b and c of the quadratic then applying the quadratic formula
