Answer:
Step-by-step explanation:
9x+2 / 6x-2 = 5x/2x+2
On cross multiply
(2x+2)(9x+2) = 5x(6x-2)
2x(9x+2)+2(9x+2) = 5x(6x-2)
18x²+4x+18x+4 = 30x²-10x
18x²+22x+4-30x²+10x = 0
-12x²+32x+4 = 0
12x²-32x-4 = 0
4(3x²-8x-1) = 0
3x²-8x-1 = 0
A=3 , b=-8 , c=-1
X = -b ± /b²-4ac ÷ 2a
= -(-8)± /(-8)²-4×3×(-1) ÷ 2×3
= 8±/64+12 ÷6
=8±/76 ÷ 6
=8±2/19 / 6
X=8+2/19 ÷ 6. , x! 8 - 2/19 ÷ 6
= 2(4+/19) ÷ 6. , = 2(4-/19) ÷ 6
= 4+/19 ÷ 3. , 4-/19 ÷ 3
