Question

Find the solutions to the equation below.

Check all that apply.
2x² +7x+3=0
A. x=2
B. x=4
C. x= 3
D. x=7
Ex=-3
F. x= -1/-2

Answer 1

E and F.

Explanation:

This can be written in quadratic formula.

x = -b +- √b² - 4ac/2a

The equation to solve is written as ax² + bx + c = 0.

a = 2, b = 7, c = 3

x = -7 +- √49 (7²) - 24 (4*2*3, or 4ac).

x = -7 +- √25

x = -7 +- 5

divide by 2a (4)

-7/4 = -1.75

5/4 = 1.25

now we do -1.75 +- 1.25

x = -1/2 (F.)

x = -3 (E.)
