Answer:
495-75=m m=420
Step-by-step explanation:
He needs to save 495 dollars, and hes already saved 75
and needs to find out how much more he needs to save to have 495 dollars

495-75=m
From here it is simple, just subtract 75 from 495 to get 420
Answer:
2 ± √3
Step-by-step explanation:
<h3>Solving quadratic equation by completing squares: </h3>
x² - 4x = -1
- Divide the coefficient of x by 2.
4 ÷ 2 = 2
- Now, square the result and add that to both sides of the equation.
2² = 2* 2 = 4
x² - 4x + 4 = -1 + 4
x² - 4x + 4 = 3
x² - 2 * x * 2 + 2² = 3
- Compare it with a² - 2ab + b² . Now , a = x and b = 2
(x - 2)² = 3
- Take square root both sides
x - 2 = ±√3
x = 2 ± √3
<h3>Solutions: x = 2 +√3 ; 2 - √3</h3>
