Hey BEN✌️, good to see you again.
Step 1: Rewrite the right side of the equation with the same base as the left side.
The equation is 3x2+2=272x−1.
Since 27=33, we can substitute this into the equation.
3x2+2=(33)2x−1
Step 2: Apply the exponent rule (am)n=amn.
3x2+2=33(2x−1)
Step 3: Equate the exponents since the bases are the same.
x2+2=3(2x−1)
Step 4: Expand the right side of the equation.
x2+2=6x−3
Step 5: Rearrange the equation into a standard quadratic form ax2+bx+c=0.
x2−6x+2+3=0
x2−6x+5=0
Step 6: Solve the quadratic equation by factoring. We need two numbers that multiply to 5 and add to -6. These numbers are -1 and -5.
(x−1)(x−5)=0
Step 7: Set each factor equal to zero to find the values of x.
x−1=0⟹x=1
x−5=0⟹x=5
The values of x are 1 and 5.
x=1orx=5
