If there is an x on both sides add or subtract it. Here's an example: 2x+10=x+8
So subtract the x and get x=-2
Or if it's negative: 5x-6=9x-11
Subtract nine x and add the 6 on the other side
-4x=-5
So divide by -4 and get x=5/4

5x(6x+28)=-23 <br><br>Help I don't understand
aksik [14]

Answer:

Solve the equation for  x  by finding  a,  b, and  c  of the quadratic then applying the quadratic formula.


Exact Form:


x  =  −  70  ±  √4210/30


Decimal Form:


x  =  −0.03


Step-by-step explanation:

5x(6x+28)=−23


Step 1: Simplify both sides of the equation.


30x2+140x=−23


Step 2: Subtract -23 from both sides.


30x2+140x−(−23)=−23−(−23)


30x2+140x+23=0


Step 3: Use quadratic formula with a=30, b=140, c=23.


x=−b±√b2−4ac/2a


x=−(140)±√(140)2−4(30)(23)/2(30)


x=−140±√16840/60


x=−7/3+1/30√4210 or x=−7/3+−1/30√4210
