Text Solution

AI Generated Solution

The correct Answer is:
To find the product of the expression \((x-2)(x+3)\) using an appropriate identity, we can use the identity for the product of two binomials: \[ (a-b)(a+b) = a^2 - b^2 \] However, in this case, we will use the general form for multiplying two binomials: \[ (x + a)(x + b) = x^2 + (a + b)x + ab \] ### Step-by-Step Solution: 1. **Identify the values of \(a\) and \(b\)**: - Here, we have \(a = -2\) (from \(x - 2\)) and \(b = 3\) (from \(x + 3\)). 2. **Apply the identity**: - According to the identity, we can express the product as: \[ (x - 2)(x + 3) = x^2 + (a + b)x + ab \] 3. **Calculate \(a + b\)**: - Substitute \(a\) and \(b\): \[ a + b = -2 + 3 = 1 \] 4. **Calculate \(ab\)**: - Now calculate the product \(ab\): \[ ab = (-2) \times 3 = -6 \] 5. **Substitute back into the identity**: - Now we can substitute \(a + b\) and \(ab\) back into the identity: \[ (x - 2)(x + 3) = x^2 + (1)x + (-6) \] 6. **Combine the terms**: - This simplifies to: \[ x^2 + x - 6 \] ### Final Answer: Thus, the product of \((x - 2)(x + 3)\) is: \[ x^2 + x - 6 \]
