Question

1.
If the roots of equation are 0 and -3. Then the
quadratic equation is?
A
x2 – 3x = 0
B
x2 + 3x + 3 = 0
с
x2 + 3x = 0
D
x² + 3x-3=0​

Answer 1

Answer:

c. x²+3x = 0

Step-by-step explanation:

let the roots are a=0 & b= -3

so the equation will be

x²-(a+b)x+ab=0

or, x²-(0-3)x+0×(-3)=0

so, x²+3x = 0
