Answer: x=1+√47 or x=1−√47 (Assuming that the "2x2" is 2x^2)
Step-by-step explanation:
Step 1: Subtract x^2+5x+39 from both sides.
2x2+3x−7−(x2+5x+39)=x2+5x+39−(x2+5x+39)
x2−2x−46=0
For this equation: a=1, b=-2, c=-46
1x2+−2x+−46=0
Step 2: Use quadratic formula with a=1, b=-2, c=-46.
x=1+√47 or x=1−√47
