Solve: 1.Square both sides of the equation.
2.Expand the left side.(3 − k)(3 − k) = 3k + 1
3.Multiply9 − 6k + k2 = 3k + 1
4.Write the quadratic equation in standard form. k2 − 9k + 8 = 0
5.Factor the quadratic equation.(k − 8)(k − 1) = 0
6.Use the zero product property.
The solutions to the quadratic equation are
.

The true solution(s) to the radical equation

(1 km=1000m, 1m=100 cm)

the result can be shown in both exact and decimal forms.

exact form; 76 · 75, 4911, 4935, 711, 735

decimal form: 5700, 4911, 4935, 711, 735

try this. the error is that sariah was combining a constant (4.5) with a variable with a coefficient, thus getting an inaccurate answer.

this is also assuming that you meant to put an equal sign before the 4.5 + x 35 x

to solve this problem, the strategy used is just to solve it yourself and find the correct answer by combining like terms.

hope this !
