simplify-0.8b^2+7.4b+(5.6b-0.2b^2)

simplify

- 0.8 b^{2} + 7.4 b + (5.6 b - 0.2 b^{2})

- b^{2} + 13 b

Solution steps

- 0.8 b^{2} + 7.4 b + (5.6 b - 0.2 b^{2})

Apply rule:

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

7.4 b + (5.6 b - 0.2 b^{2}) = 7.4 b + 5.6 b - 0.2 b^{2}

= - 0.8 b^{2} + 7.4 b + 5.6 b - 0.2 b^{2}

Add similar elements:

7.4 b + 5.6 b = 13 b

= - 0.8 b^{2} + 13 b - 0.2 b^{2}

Group like terms

= - 0.8 b^{2} - 0.2 b^{2} + 13 b

Add similar elements:

- 0.8 b^{2} - 0.2 b^{2} = - b^{2}

= - b^{2} + 13 b

\frac{( 0 ^{2} + 1 )}{3}

∣ 2 x ∣ + 4 < 7
