3 0
2x² + 4x - 3 = 0
x = <u>-(4) ± √((4)² - 4(2)(-3))</u>
                   2(2)
x = <u>-4 ± √(16 + 24)</u>
                 4
x = <u>-4 ± √(40)
</u>             4<u>
</u>x = <u>-4 ± 2√(10)
</u>              4<u>
</u>x = -1 ± ¹/₂√(10)
x = -1 + ¹/₂√(10)    U    x = -1 - ¹/₂√(10)

3/4 yard long and 1/2 yard tall what is the area of the poster frame
zmey [24]
The area is 3/8 yd².

Area = length x width

Given:
length = 3/4 yard
width = 1/2 yard

Area = 3/4 yd * 1/2 yd
Area = 3*1/4*2
Area = 3/8 yd²

In multiplying fractions, multiply the numerators, then, multiply the denominators. lastly, simplify the fraction. 3/8 yd² is already in its simplest form.
