Princess Poly claims that the equation (3x−4i)(7x−8)(3x+4i)=0 has three roots, a real root and a complex root with a multiplicit
Serjik [45]

Given equation:

(3x-4i)(7x-8)(3x+4i)=0

i.e., 3x-4i=0       and       7x-8=0       and       3x+4i=0

i.e., 3x=4i       and       7x=8       and       3x=-4i

i.e., x=\frac{4i}{3}       and       x=\frac{8}{7}       and       x=-\frac{4i}{3}

Therefore, the given equation has a real root i.e., x=\frac{8}{7}

and two complex conjugate roots i.e., x=\frac{4i}{3} and x=-\frac{4i}{3}

Hence, option C is correct.

How do you solve this step by step?
kolezko [41]

Answer:

90

Step-by-step explanation:

Evaluate x^2 + 2 x^2 + 3 x^2 + 4 x^2 where x = 3:

x^2 + 2 x^2 + 3 x^2 + 4 x^2 = 3^2 + 2×3^2 + 3×3^2 + 4×3^2

3^2 = 9:

3^2 + 2×9 + 3×3^2 + 4×3^2

3^2 = 9:

3^2 + 2×9 + 3×9 + 4×3^2

3^2 = 9:

3^2 + 2×9 + 3×9 + 4×9

3^2 = 9:

9 + 2×9 + 3×9 + 4×9

2×9 = 18:

9 + 18 + 3×9 + 4×9

3×9 = 27:

9 + 18 + 27 + 4×9

4×9 = 36:

9 + 18 + 27 + 36
