Hello :
f(x) = (x-5)(x+2i)
= x² +2ix -5x-10i
f(x) = x² +(2i-5)x -10i
<span>coefficients : a =1 b = 2i-5 c =-10i</span>
Answer:
<u>D</u>
Step-by-step explanation:
The logical step is to <u>factorize the left side of the equation</u>, which becomes:
Then, you can take the square root on both sides.
Not asked, but good to understand the procedure regardless.
Given: 48 students took the exam.
A total of 18 + 10 = 28 students scored 80% or above.
To find the percentage, take the part (28 students) divided by the whole (48 students) then multiply the quotient by 100.
(28 students / 48 students) x 100 = 58.33%
58.33% of the students who took the exam scored an 80% or higher
