Multiply the polynomials (4x+1)(4x+1) and (3x+5)(-3x+5).

STEP 1

Assumptions
1. We are multiplying two binomials: (4x+1)(4x + 1) and (3x+5)(-3x + 5).
2. To multiply the binomials, we will use the distributive property (also known as the FOIL method, which stands for First, Outer, Inner, Last).

STEP 2

First, we multiply the first terms from each binomial.
First=4x(3x)First = 4x \cdot (-3x)

STEP 3

Calculate the product of the first terms.
First=12x2First = -12x^2

STEP 4

Next, we multiply the outer terms from each binomial.
Outer=4x5Outer = 4x \cdot 5

STEP 5

Calculate the product of the outer terms.
Outer=20xOuter = 20x

STEP 6

Now, we multiply the inner terms from each binomial.
Inner=1(3x)Inner = 1 \cdot (-3x)

STEP 7

Calculate the product of the inner terms.
Inner=3xInner = -3x

STEP 8

Finally, we multiply the last terms from each binomial.
Last=15Last = 1 \cdot 5

STEP 9

Calculate the product of the last terms.
Last=5Last = 5

STEP 10

Combine the products from the First, Outer, Inner, and Last steps to get the expanded form of the polynomial.
Expandedform=First+Outer+Inner+LastExpanded\, form = First + Outer + Inner + Last

STEP 11

Substitute the calculated products into the expanded form.
Expandedform=12x2+20x3x+5Expanded\, form = -12x^2 + 20x - 3x + 5

STEP 12

Combine like terms to simplify the expression.
Simplifiedform=12x2+(20x3x)+5Simplified\, form = -12x^2 + (20x - 3x) + 5

STEP 13

Finish combining like terms.
Simplifiedform=12x2+17x+5Simplified\, form = -12x^2 + 17x + 5
The product of the polynomials (4x+1)(3x+5)(4x + 1)(-3x + 5) is 12x2+17x+5-12x^2 + 17x + 5.
