PLS SHOW UR SOLUTIONS

Answer:

Q1. $(2x-3)^{2}+3(x-4)=5+y\\$

$4x^{2} -12x+9+3x-12-5-y=0$

$4x^{2} -9x-8-y=0$

$4x^{2} -9x-8=y$

∴ $y = 4x^{2} -9x-8$

∴ From the quadratic equation above, a = 4, b = -9, and c = -8.

Q2. $(x-5)^{2} -x^{2} =y$

$x^{2} -10x+25-x^{2} =y$

$-10x+25=y$

∴ $y = -10x + 25$

∴ The equation above is not a quadratic equation as it does not follow the format of ax² + bx + c.

Q3. $2x(4x^{2} -4x+1)=y+x(8x)+4(2x)$

$8x^{3} -8x^{2} +2x-8x^{2} -8x=y$

∴ $y=8x^{3} -16x^{2} -6x$

∴ The equation above is not a quadratic equation as it does not follow the format of y = ax² + bx + c.
