If the discriminant is positive, then the solution will be

• one real solution

• two real solutions

• no real solutions

• one imaginary solution

• A
• B
• C
• D

Match the following regarding the discriminant.

• there are 2 complex roots/solutions

• If the discriminant is less than 0,

• there is one real solution

• If the discriminant is equal to 0,

• there are two real solutions

• If the discriminant is greater than 0,

Say 'TRUE' or 'FALSE'
A quadratic equation ax² + bx + c = 0 has equal roots, then b² - 4ac = 0 

• TRUE

• FALSE

If there is one solution, the discriminant is . . .

• zero

• a postive number

• a negative number

• a perfect square
