Evaluate the product of $(x + 5) (x - 2)$

Open in App

Solution

The given polynomials are $x + 5$ and $x - 2$ we multiply them as follows:

$(x + 5) (x - 2) = (x \times x) + (x \times - 2) + (5 \times x) + (5 \times - 2) = x^{2} - 2 x + 5 x - 10 = x^{2} + 3 x - 10$

Hence, $(x + 5) (x - 2) = x^{2} + 3 x - 10$ .
