Question

Find the discriminant and comment on the roots of the equation: 4x2 + 10x + 7 = 0

Answer 1

Answer:

Discriminant. Discriminant, in mathematics, a parameter of an object or system calculated as an aid to its classification or solution. In the case of a quadratic equation ax2 + bx + c = 0, the discriminant is b2 − 4ac; for a cubic equation x3 + ax2 + bx + c = 0, the discriminant is a2b2 + 18abc − 4b3 − 4a3c − 27c2.

Answer 2

Step-by-step explanation:

4x²+10x+7=0

delta=b²-4ac

100-28x4=100-112

-12

roots will be alpha +beta=-10/4=-5/2

and product =7/4 is the answer of this
