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

Solution

simplify

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

Solution

- 4 x^{2} + 7 x - 1

Solution steps

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

Apply rule:

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

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

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

Expand

2 x (3 - 2 x) : 6 x - 4 x^{2}

= 6 x - 4 x^{2} + x - 1

Group like terms

= - 4 x^{2} + 6 x + x - 1

Add similar elements:

6 x + x = 7 x

= - 4 x^{2} + 7 x - 1
