Solve 3x2 + 4x + 2 = 0 by using the Quadratic Formula. If necessary, round to the nearest hundredth.
viva [34]

Answer:

Step-by-step explanation:

For this equation: a=3, b=4, c=2

3x2+4x+2=0

Step 1: Use quadratic formula with a=3, b=4, c=2.

x= −b±√b2−4ac / 2a

x= −(4)±√(4)2−4(3)(2)  /  2(3)

x= −4±√−8  /  6

Answer:

No real solutions.

Solve the system by substitution. -4.5-2y=-12.5 , 3.35x-y=-0.75
goldenfox [79]
First, we solve for y in the first equation:
-2y = -12.5 +4.5
-2y=-8
y= \frac{8}{2}
y=4
Then, we substitute the y value in the other equation and solve for x:
3.35x-(4)=-0.75
3.35x=-0.75+4
3.35x=3.25
x= \frac{3.25}{3.35}
x= \frac{65}{67}

Solve 4(x + 1) = 4x + 4. Would it be No solution? Or all real numbers?
arsen [322]
Pick any number. Write it in place of 'x'. If the result is a true statement, then your number is a solution of the equation. Do it again with a different number. Then do it again. Does it matter what your number is ?
