Answer:
Step-by-step explanation:
2x²-2x=3
2x²-2x -3 = 0
note :
the discriminat of each quadratic equation : ax²+bx+c=0 ....(a ≠ 0) is :
Δ = b² -4ac
1 ) Δ > 0 the equation has two reals solutions : x = (-b±√Δ)/2a
2 ) Δ = 0 : one solution : x = -b/2a
3 ) Δ < 0 : no reals solutions
***** in this exercice : a = 2 b = -2 c = -3
Δ = (-2)² -4(2)(-3) =28
x = (2±√28)/6
5.56 rounded to the nearest tenth is 5.6
hope this helps
since 6 is greater than 5

The third answer is right. Scientific notation is always expressed with
one digit before the decimal and is multiplied by the power of ten to
compensate for the offset.
Also when writing without access to superscript use either of these methods to express the exponent.
