Write the quadratic equation whose roots are 1 and - 1, and whose leading coefficient is 3. (Use the letter x to represent the variable.)



Answer :

Answer:

Step-by-step explanation:

If the roots are 1 and -1 the quadratic looks like this:

y = (x-1)(x+1)       to get a leading coefficient of '3'...multiply it by 3

y = 3 (x-1)(x+1)       now you can expand it

y = 3x^2 -3          Done.
