Answer:

(A) - (5)

(B) - (4)

(C) - (1)

(D) - (2)

Step-by-step explanation:

(A) We are given the polynomial (x+4)(x−4)[x−(2−i)][x−(2+i)]

(5) The related polynomial equation has a total of four roots; two roots are complex and two roots are real.

(B) We are given the polynomial (x+i)(x−i)(x−2)³(x−4).

(4) The related polynomial equation has a total of six roots; two roots are complex and one of the remaining real roots has a multiplicity of 3.

(C) We are given the polynomial (x+3)(x−5)(x+2)²

(1) The related polynomial equation has a total of four roots; all four roots are real and one root has a multiplicity of 2.

(D) We are given the polynomial (x+2)²(x+1)²

(2) The related polynomial equation has a total four roots; all four roots are real and two roots have a multiplicity of 2. (Answer)

Please can someone help me with this question

<em>Answer:</em>

<em>r = -</em> $\frac{6a}{1-5m^2}$ <em />

<em>Step-by-step explanation:</em>

<em>Rewrite the equation as </em> $\sqrt{x} 6a+r/5r$ <em> = m</em>

<em>Remove the radical on the left side of the equation by squaring both sides of the equation.</em>

<em>(</em> $\sqrt{\frac{6a+r}{5r} )^{2}$ <em> = m^2</em>

<em>Then, you simplify each of the equation. </em>

<em>Rewrite: (</em> $\sqrt{\frac{6a+r}{5r} )^{2}$ <em> as </em> $\frac{6a+r}{5r} = m^{2}$ <em />

<em>Remove any parentheses if needed.</em>

<em>Solve for r. </em>

<em>Multiply each term by r and simplify."</em>

<em>Multiply both sides of the equation by 5.</em>

<em>6a+r= m^2r⋅(5)</em>

<em>Remove parentheses.</em>

<em>Move 5 to the left of (m ^2) r </em>

<em>6a+r=5m^2)r</em>

<em>Subtract 5m^2)r from both sides of the equation.</em>

<em>6a+r-5m^2)r=0</em>

<em>Subtract 6a from both sides of the equation.</em>

<em>r-5m^2)r=-6a</em>

<em>Factor r out of r-5m^2)r </em>

<em>r(1-5m^2)=-6a</em>

Divide each term by 1-5m^2 and simplify.

r = - $\frac{6a}{1-5m^2}$

There you go, hope this helps!
