No, a cubic equation can not have three complex roots. This is because it turns twice and one end goes to positive infinity and one end goes to negative infinity. Thus, one of these MUST cross the x-axis at some point, meaning y = 0 and a real root exists.
Yes, a cubic equation can have three real roots if it cuts the x-axis three times.
7/12 divided by 2/5 is 35/24
Answer:
Step-by-step explanation:
Jamie is correct.
two angles are equal in an isosceles triangle.
let the angles be x,x,y
if she knows x
then y=180-(x+x)=180-2x
so she can find y
similarly if she knows y then she can calculate x.
