Question

How many real number solutions are there to the equation 0 = –3x² + x – 4?

Answer 1

can you find the value of the discriminant?

Answer 2

the value of what? i have no clue

Answer 3

when ever you required to know nature of roots then always always use discriminant. good luck . others are here to help you. good luck again.

Answer 4

for a quadratic \[ax^2 + bx + c = 0\]

use the discriminant

\[\Delta = b^2 - 4ac \]

in your question a=-3, b = 1 and c= -4

then 1^2 - 4 x (-3) x (-4) = -47

since \[\Delta < 0\] no real solutions

Rules

\[\Delta > 0\] 2 unequal real solutions

if \[\Delta\] is a square number the roots are rational.

\[\Delta = 0\] repeated or equal roots

and the senario above
