Step-by-step explanation:
1-x + 3 =3x +2x+1
2 4 6+x
2-2x+6 = 18x²+2x+1
4 6+x
(-2x+6)(6+x)=(18x²+2x+1)(4)
-12x-2x²+36+6x=72x²+8x+4
-2x²-6x+36=72x²+8x+4
72x²+2x²+8x+6x+4-36=0
74x²+14x-32=0
2(37x²+7x-16)=0
37x²+7x-16=0
a=37
b=7
c=-16
D=b²-4ac
D=(7)²-4(37)(-16)
D=49+640
D=689
x=-b+√D. x=-b+√D
2a. 2a
x=-7+√689. x=-7-√689
74. 74
