Question

Find the roots of the quadratic equation by using the quadratic formula.

        x2 - 3x - 6 = 0​

Answer 1

Step-by-step explanation:

by using formula

D= b²-4ac

D= (3)²- 4× 2× 6

D= 9- 4-× 2

D= 9-8

D = 1

ITS A POSITIVE NO. SO,

-B-/D÷2×A = -3-ROOT1÷4

-B+ROOT D ÷ 2A = -3+ROOT D ÷ 4
