simplify [x-1(x+2)]-(3x+1)

simplify

[x - 1 (x + 2)] - (3 x + 1)

- 3 x - 3

Solution steps

(x - 1 \cdot (x + 2)) - (3 x + 1)

Apply rule:

(a) = a

(x - 1 \cdot (x + 2)) = x - 1 \cdot (x + 2)

= x - 1 \cdot (x + 2) - (3 x + 1)

1 \cdot (x + 2) = x + 2

- (3 x + 1) = - 3 x - 1

= x - (x + 2) - 3 x - 1

Expand

- (x + 2) : - x - 2

= x - x - 2 - 3 x - 1

Group like terms

= x - x - 3 x - 2 - 1

Add similar elements:

x - x - 3 x = - 3 x

= - 3 x - 2 - 1

Subtract the numbers:

- 2 - 1 = - 3

= - 3 x - 3

\frac{5}{2} \cdot \frac{5}{4}

(3 \cdot 4)^{2 \cdot (- 1)}

(5^{- 2})^{- 2}

\frac{4 - x}{x ^{2} + 2 x - 24}

5 \frac{1}{8} + 6 \frac{3}{20} + 1
