simplify (-4x+1)-(-7x^2+4x+2)

simplify

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

7 x^{2} - 8 x - 1

Solution steps

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

Apply rule:

(a) = a

(- 4 x + 1) = - 4 x + 1

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

Apply the distributive law:

- (- a + b) = a - b

- (- 7 x^{2} + 4 x + 2) = 7 x^{2} - 4 x - 2

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

Group like terms

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

Add similar elements:

- 4 x - 4 x = - 8 x

= 7 x^{2} - 8 x + 1 - 2

Subtract the numbers:

1 - 2 = - 1

= 7 x^{2} - 8 x - 1

(a + h) (a + h) (a + h)

7 + 48

14 - 3 (4 n - 1)

2^{5} \cdot 2^{- 7}
