Question

we can find roots of quadratic
equation if b²-4ac<0 (True/false)​

Answer 1

Answer:

TRUE

Step-by-step explanation:

If b2 - 4ac = 0 then the roots will be x = −b±02a = −b−02a, −b+02a = −b2a, −b2a. Clearly, −b2a is a real number because b and a are real. Thus, the roots of the equation ax2 + bx + c = 0 are real and equal if b2 – 4ac = 0.

Answer 2

Answer:

yes its true

Step-by-step explanation:

we can find roots of quadratic equations by simplifying them

it is b squared so it should also have root

4 also have root which is 2

so hence, true
