Compute the value of the discriminant and give the number of real solutions of the quadratic equation.

Sergio039 [100]

$-2x^2+6x-3=0 \\ \\
a=-2 \\ b=6 \\ c=-3 \\ \Delta=b^2-4ac=6^2-4 \times (-2) \times (-3)=36-24=12$

The value of the discriminant is 12.
Since the discriminant is greater than zero, the equation has two real solutions.

Find measurement of arc JL.

Tresset [83]

4x-2 + 7x-18 + 6x+6 = 360 degrees

combine like terms

17x-14 = 360

add 14 to both sides

17x =374

divide both sides by 17
x = 374 / 17 = 22

JL = 7x-18
replace x with 22 and calculate
7(22) - 18 = 154 -18 = 136 degrees
