Solve x2 - 8x + 3 = 0 by completing the square. Which equation is used in the process? ( x - 4) 2 = 0 ( x - 4) 2 = 19 ( x - 4) 2 = 13 Use a table of function values to approximate an x-value in which the exponential function exceeds the polynomial function. f(x) = 3(3)(2x-5) h(x) = (x + 1)5 + 4 x = 5 x = 6 x = 7 x = 8
do you know how you make square complete from these x^2 -8x +3 = 0 ?
suppose -8x you get assuming -4+(-4) = -8 so what mean this ? how many need be the ,,c" term in place of 3 ?
hope you know the standard form of a quadratic Ax^2 +Bx +C = 0
B = -4+(-4) = -8 C = -4*(-4) = ?
C = 16
how you make from +3 this 16 ? how many you need adding to +3 to get +16 ?
that exam
i like make you understanding step by step @AZ
@Shadow
ok x^2 -8x +3 = 0 x*x -4x-4x +3 +13 -13 = 0 x*x -4x-4x +4*4 = 13 x(x-4) -4(x-4) = 13 (x-4)(x-4)=13 (x-4)^2 = 13 hope helped understandably easy
@b1az3
@dizzymustang156 opinion pls ? ty.
amazing
hope you know the way how you complet a quadratic to be perfect square ...,
