Welcome to Math Help Forum!Let .Then2. (root of x) - 2 = 4th root of x
Solve this quadratic for . Then put again at the end.
You know that . So square both sides of3. (root of 3-3x) - (root of 3x + 2) = 3
Now solve this quadratic.
Use the quadratic formula. You know that4. write a quad equation with integer coef who roots are
(-1 +- root of -2) / 2
So start with and see what value this gives for . If it's a fraction, multiply both sides of by something that will get rid of fractions.
For real unequal roots,7. find all p in f(x) = (p + 1) x^2 + px - 1 so that the quadratic equation's roots are real and unequal
What is the only value of for which this is not true?
