Will give brainliest to best answer- due today use the quadratic formula to solve x^2-4x+3, show your work. then describe the solution.

Firstly, using our equation plug in the values into our equation (a = 1, b = -4, and c = 3):

Next, solve the exponent and multiplications:

Next, solve the subtraction:

Next, solve the square root:

Next, you are going to solve this equation twice - once with the  + symbol, once with the - symbol as such:

Your zeros (x-intercepts) are 3 and 1. These solutions are real and rational.

answer: cos [   arcsin (3/5) - arccos (1/2) ] =

step-by-step explanation: × = 3/5 = 0.6--> x = 36.87 and x = 180 - 36.87 = 143.13 deg

cos y = 1/2 --> y = +- 60 deg a. cos (x - y) = cos (143.13 - 60) = cos 83,13  

=

0.12

b. cos (36.87 - 60) = cos (-23.23) = 0.92
