Answer 1

To multiply the polynomials (1-7x)(1+9x), use the distributive property and combine like terms.

Step-by-step explanation:

To multiply the polynomials (1-7x)(1+9x), we use the distributive property. We multiply each term in the first polynomial by each term in the second polynomial and combine like terms. In this case, we have:

<(1-7x)(1+9x) = 1*1 + 1*9x + (-7x)*1 + (-7x)*9x Simplifying this expression, we get: 1 + 9x - 7x - 63x^2 Combining like terms, we have: -63x^2 + 2x + 1
