Solve the quadratic equation (√5 – 3)x^2 + 3x + (√5+3) = 0, giving your answers in the form a+b√5, where a and b are constants.

Step-by-step explanation:

For a quadratic equation ax² + bx + c ,

its roots are =

In the question ,

Quadratic equation = (√5 - 3)x² + 3x + (√5 + 3)

By using quadratic formula ,

Rationalizing the roots ,

$53.50

step-by-step explanation:

you have to subtract the amount of money chuck earned ($72.50) by the cost of the gas for the mower ($11.25) and the new string for the trimmer he bought ($7.75).

72.50-11.25=61.25

and then subtract $61.25 by the second thing he bought (the new string for the trimmer)

61.25-7.75=53.5

so in total it's $53.50 (53 dollars and 50 cents)
