Howard is interested in increasing the proportion of whole grains in his diet. Which substitution would best accomplish that?

Multiply and simplify the following radical expressions. −6(8+5)

Solve the following quadratic equation using the quadratic formula. 16y2+24y=−9

In addition to dietary sources, glucose can be derived from 

Find the product of the binomials using the appropriate special product (difference of two squares, square of a binomial sum, or square of a binomial difference). (x+2)(x−2)

Completely factor the expression, if possible. 64y3−x3

Multiply the polynomials using the distributive property and combine like terms. (x2−x−1)(x−9)

Simplify the expression.  The final form of the expressions with variables should contain only positive exponents.  Assume that all variables represent nonzero numbers.  ( − 2 x 3 y 5 ) ( − 6 x 5 y − 8 )

Multiply the polynomials using the distributive property and combine like terms. (−x+3)(7x+5)

Simplify the expression.  The final form of the expressions with variables should contain only positive exponents.  Assume that all variables represent nonzero numbers.  ( − 6 x 4 y 5 ) ( − 6 x 3 y − 8 )
