Answer to Problem 8AYU

The statement is false.

Explanation of Solution

Given information:

The given statement is “If 2−3i is a solution of quadratic equation with real coefficients, then −2+3i is also a solution”.

Calculation:

The standard form a complex number is a+ib .

The conjugate of complex number is obtained by adding a minus sign before the imaginary part.

The conjugate is thus expressed as,

a−ib .

A quadratic number has two solutions and if the root of a quadratic equation is complex then its other root will be conjugate.

If one solution is 2−3i then the other solution will be 2+3i .

Therefore, the given statement is false.
