The missing term in the provided quadratic equation is 10x if the roots of a quadratic equation are 5 ± 3i.

<h3>What is a complex number?</h3>

It is defined as the number which can be written as x+iy where x is the real number or real part of the complex number and y is the imaginary part of the complex number and i is the iota which is nothing but a square root of -1.

The question is incomplete.

The complete question is in the picture, please refer to the attached picture.

We have the roots of a quadratic equation:

5 ± 3i

To find the quadratic equation:

(x - (5+3i))(x - (5-3i))

\rm =x^2+x\left(-\left(5-3i\right)\right)-\left(5+3i\right)x-\left(5+3i\right)\left(-\left(5-3i\right)\right)

= x² -10x + 34

The missing value is 10x

The quadratic equation is:

= x² -10x + 34

Thus, the missing term in the provided quadratic equation is 10x if the roots of a quadratic equation are 5 ± 3i.

Classify the four angles of the quadrilateral. B 105° A .90° 75° C 90° D LA LB 4C ZD Right Acute Obtuse O X O O Ś ?
earnstyle [38]

The picture has a quadrilateral with ABCD angles.

∠A=90° is right angle

∠B=105° is obtuse angle

∠C=75° is acute angle

∠D=90° is right angle

Given that,

The picture has a quadrilateral with ABCD angles.

The angle are

∠A=90°

∠B=105°

∠C=75°

∠D=90°

We have to clarify the angles of the quadrilateral.

∠A is right angle because the right angle is created when two straight lines cross at a 90° angle or when they are perpendicular at the intersection.

∠B is obtuse angle because a form of angle known as an obtuse angle is one that is always greater than 90° but less than 180°.

∠C is acute angle because an acute angle is one that is smaller than 90 degrees in length. L-shape shapes at 90°

∠D is right angle because the right angle is created when two straight lines cross at a 90° angle or when they are perpendicular at the intersection.
