1+8x7=57 but (1+8)x7=63. I'm not sure what you're looking for.
16x2 - 56x + 49 = (4x - 7)2
y = -16x2 + 342At the x-intercepts, y=0-16x2 + 342 = 016x2 = 342x2 = 342/16 = 21.375x = plus and minus sqrt(21.375) = approx. plus and minus 4.6233 (rounded)

if you want to be specific, the equation should look like this:\ (10x10) + (8x7) so... 100 + 56 equals 156! try it in a calculator

-16x2 + x + 8 = -1/64(32x - 1 - √513)(32x - 1 + √513)
16x2 - 56x + 49 = (4x - 7)2
16x2 + 40x + 25 = 16x2 + 20x + 20x + 25 = 4x(4x + 5) + 5(4x + 5) = (4x + 5)(4x + 5) = (4x + 5)2
y = -16x2 + 342At the x-intercepts, y=0-16x2 + 342 = 016x2 = 342x2 = 342/16 = 21.375x = plus and minus sqrt(21.375) = approx. plus and minus 4.6233 (rounded)
