Question

Write the quadratic equation whose roots are -6 and 1, and whose leading coefficient is 3 .

Answer 1

x^2 - (A+B)x + A.B = 0

where A,B are the roots

Answer 2

they give you the roots so (x+6) and (x-1)

Answer 3

(x+6)(x-1) FOIL it out and you get
x^2+5x-6

Answer 4

then to get the leading coefficient to 3 just multiply the whole thing by 3
3(x^2+5x-6)
