Question

if hcf & lcm of 9 &12 are the roots if a quadrativ equation. then find the quadratic equation​

Answer 1

Answer:

x² - 39x + 108 = 0

or. x² - 39x = -108

Step-by-step explanation:

hcf = 3. LCM = 36

roots are. 3 and 36

we do factorisation by splitting the middle term

in reverse order

therefore. (x - 3)*(x - 36) = 0

therefore. x² - 36x - 3x + 108 = 0

therefore. x² - 39x + 108 = 0

or. x² - 39x = -108

is the quadratic equation
