What is the discriminant of 2x² 5x 3 0?

Answers

Answer 1

The discriminant of a quadratic equation is equal to the expression (b^2 - 4ac) where a, b, and c are the coefficients of the equation. In this case, the discriminant is equal to (5^2 - 4(2)(3)) = 25 - 24 = 1.

The discriminant of a quadratic equation is a numerical value that can be used to determine the nature of its roots. The discriminant is equal to the expression (b^2 - 4ac) where a, b, and c are the coefficients of the equation. In this case, the equation is 2x² 5x 3 0. We can identify the coefficients of the equation as a = 2, b = 5, and c = 3. Using the formula, the discriminant is equal to (5^2 - 4(2)(3)) = 25 - 24 = 1. This means that the equation has two real and equal roots, as the discriminant is equal to zero. This can be seen by factoring the equation, which gives us (2x - 3)(x + 1) = 0. The roots of the equation are then x = 3/2 and x = -1.

Discriminant = b^2 - 4ac

= (5)^2 - 4(2)(3)

= 25 - 24

= 1

Answer:

x = 10

Step-by-step explanation:

The opposite angles in a parallelogram are congruent, then

5x - 9 = 3x + 11 ( subtract 3x from both sides )

2x - 9 = 11 ( add 9 to both sides )

2x = 20 ( divide both sides by 2 )

m∠c =?? degrees


° m∠d =?? degrees

Answers

Answer:

Step-by-step explanation:

This figure better be a square, otherwise there is no answer.

The diagonals of a square intersect at right angles, so d = 90 degrees. That property comes from the rhombus.

Squares have equal sides and the opposite sides are parallel. The triangle containing c is isosceles. The lower right corner is a right angle. So c must equal 45 degrees since the angle on the lower left must equal 45 degrees as well

Answer

c = 45

d = 90
