Expand the equation by multiplying it with itself: (x-3)*(x-3)

x^2 - 3x - 3x + 9 = 5
x^2 - 6x + 9 = 5
x^2 -6x +4 = 0

Since this is not part of the choices, try a different approach. Take the square root of both sides:

x - 3 = square root of 5
x - 3 = +/- 2.24

I guess this is the middle term which is incomplete. The first and last choices are not equivalent to the given equation.

LUCKY_DIMON [66]

Answer:

Step-by-step explanation:

Δ = 4^{2}  - 4 * 4 * (-63)  =  16 + 16 * 63 = 16 * (1 + 63) = 16 * 64

VΔ = 4 *  8 = 32

a = (- 4 ± 32) * \frac{1}{8}

a' = 7/2

a''= 9/2

Your answer is option c. The final simplified form should have y to the 4th power instead of y cubed. I think so..
