Web28 sep. 2024 · Based on the discriminant value, how many real number solutions does the equation have? Remember that the discriminant is calculated using the coefficents a, b and c. Given 0 = -2x^2 + 0x + 3, the coeff. are a=-2, b=0 and c=3. The discriminant is b^2 - 4ac. Here, the discriminant is 0^2 - 4 (-2) (3) = 24. WebThe discriminant is the part of the quadratic formula underneath the square root symbol: b²-4ac. The discriminant tells us whether there are two solutions, one solution, or no solutions.

Web13 okt. 2024 · Determine number of solution through discriminant: two identical roots Answer: two identical roots Rearrange terms in descending order: x 2 − x + 1 4 = 0 Find discriminant of quadratic equation through (b^2-4ac ): Δ = b 2 − 4 a c Identify a,b,c througn coefficient: { a = 1 b = − 1 c = 1 4 WebThis is the key to knowing how many solutions we have: If b2 - 4 ac is positive (>0) then we have 2 solutions. If b2 - 4 ac is 0 then we have only one solution as the formula is reduced to x = [- b ± 0]/2 a. So x = -b/2 a, giving only one solution. Lastly, if b2 - 4 ac is less than 0 we have no solutions.
