3x^2 + 4x - 5 = 0
x = [-b ±√(b^2 - 4ac)]/2a
a = 3
b = 4
c = -5
x = [-4 ±√(16 + 60)]/6
x = [-4 ±√76]/6
x = [-4 ±√(2^2 * 19)]/6
x = [-4 ±2√19]/6
x = [-2 ±√19]/3
x = [-2 + √19]/3
x = [-2 + 4.35]/3
x = 2.35/3
x = 0.78 (rounded to the nearest hundredth)
x = [-2 - ±√19]/3
x = [-2 - 4.35]/3
x = -6.35/3
x = -2.12 (rounded to the nearest hundredth)
<span>∴ x = -2.12 , 0.78 (rounded to the nearest hundredth)</span>
Multiplication property of equality can be used to solve:
Step-by-step explanation:
First of all, lets define the multiplication property of equality
The multiplication property of equality states that if one side of an equation is multiplied with any number the other side is also multiplied with the number.
Given equations are:
By observing the equations we can see that only third equation has a fraction in it so it has to be multiplied with -2 for solution
Hence,
Multiplication property of equality can be used to solve:
