simplify (x-1)^2+(2x+5)

Solution

simplify

(x - 1)^{2} + (2 x + 5)

Solution

x^{2} + 6

Solution steps

(x - 1)^{2} + (2 x + 5)

Apply rule:

a + (b + c) = a + b + c

(x - 1)^{2} + (2 x + 5) = (x - 1)^{2} + 2 x + 5

= (x - 1)^{2} + 2 x + 5

Expand

(x - 1)^{2} : x^{2} - 2 x + 1

= x^{2} - 2 x + 1 + 2 x + 5

Group like terms

= x^{2} - 2 x + 2 x + 1 + 5

Add similar elements:

- 2 x + 2 x = 0

= x^{2} + 1 + 5

Add the numbers:

1 + 5 = 6

= x^{2} + 6
