Question and answer
Write the quadratic equation whose roots are 4 and 5 , and whose leading coefficient is 4 .
the quadratic equation whose roots are 4 and 5 , and whose leading coefficient is 4 is 4x^2 - 36x + 80 = 0. Roots are 4 and 5: (x - 4)(x - 5) = 0 leading coefficient is 4: (4x - 16)(x - 5) = 0 find the product: 4x^2 - 20x - 16x + 80 =0 simplify the equation: 4x^2 - 36x + 80 = 0

the quadratic equation whose roots are 4 and 5 , and whose leading coefficient is 4 is 4x^2 - 36x + 80 = 0.
Roots are 4 and 5: (x - 4)(x - 5) = 0
leading coefficient is 4: (4x - 16)(x - 5) = 0
find the product: 4x^2 - 20x - 16x + 80 =0
simplify the equation: 4x^2 - 36x + 80 = 0

the quadratic equation whose roots are 3 and 6 , and whose leading coefficient is 2 is 2x^2 - 18x + 36 = 0
Roots are 3 and 6, then (x - 3)(x - 6) = 0
leading coefficient is 2, then (2x - 6)(x - 6) = 0
2x^2 - 12x - 6x + 36 = 0
2x^2 - 18x + 36 = 0
