Question

Your answer should be a polynomial in standard form. x+7 x+3

Answer 1

The expression ((x - 7)(x - 3)) in standard form is (x² - 10x + 21).

To write the expression ((x - 7)(x - 3)) in standard form, we need to multiply the two factors and simplify the resulting expression. Using the distributive property of multiplication, we get:

`[(x - 7)(x - 3) = x(x - 3) - 7(x - 3) = x^2 - 3x - 7x + 21]`

Simplifying the expression, we get:

`[x^2 - 10x + 21]`

Therefore, the expression ((x - 7)(x - 3)) in standard form is (x² - 10x + 21).
