Question

D. Write the quadratic equation in the standard form: ax² + bx + c = 0 given the following roots.

Use the formula: Sum: ×1 + ×2 =-b/a ; Product: ×1 . ×2= c/a ; Equation: x² + b/a x + c/a =0

1. 2 and 9

2. -5 and 6

help me plss....

Answer 1

Answer:

eqn:x^-(sum of roots)+(product of roots)=0

1. x^2-(2+9)+(2×9)=0

or,x^2-11x+18=0

2.x^2-(-5+6)+(-5)×6=0

or,x^2-x-30=0
