1) Expand and s a) \( 3\left(x^{2}+3 x\right. \) b) \( -2\left(p^{2}-3\right. \)

Sure! Let's expand and simplify each expression step by step. --- ### 1) Expand and Simplify #### a) \( 3\left(x^{2} + 3x\right) \) **Step 1:** Distribute the **3** to each term inside the parentheses. \[ 3 \times x^{2} + 3 \times 3x \] **Step 2:** Perform the multiplication. \[ 3x^{2} + 9x \] **Final Answer:** \[ 3x^{2} + 9x \] --- #### b) \( -2\left(p^{2} - 3\right) \) **Step 1:** Distribute the **-2** to each term inside the parentheses. \[ -2 \times p^{2} + (-2) \times (-3) \] **Step 2:** Perform the multiplication. \[ -2p^{2} + 6 \] **Final Answer:** \[ -2p^{2} + 6 \] --- If you have any more expressions you'd like to expand or simplify, feel free to ask!
