simplify 2|a+b|+3|a-b|-|b|^2

simplify

2 ∣ a + b ∣ + 3 ∣ a - b ∣ - ∣ b ∣^{2}

2 ∣ a + b ∣ + 3 ∣ a - b ∣ - b^{2}

Solution steps

2 ∣ a + b ∣ + 3 ∣ a - b ∣ - ∣ b ∣^{2}

Apply absolute rule:

∣ a ∣^{n} = a^{n}

, assuming

n i s e v e n, a \in ℜ

∣ b ∣^{2} = b^{2}

= 2 ∣ a + b ∣ + 3 ∣ a - b ∣ - b^{2}
