Answer: [tex]\boxed{Sol=\{\dfrac{7}{4} \}}\\[/tex]

I suppose 17x^ means 17x².

and that we must solve the equation.

Step-by-step explanation:

[tex](x-3)(x-5)-(4x+1)(1-4x)=14x^2\\\\x^2-3x-5x+15+(4x+1)(4x-1)=17x^2\\\\x^2-8x+15+16x^2-1=17x^2\\\\-8x+14=0\\\\8x=14\\\\x=\dfrac{7}{4} \\\\\boxed{Sol=\{\dfrac{7}{4} \}}\\[/tex]
