Question

(x2 + 3x + 4)(2x2 + 4x + 7)

Answer 1

hmmm oooooooooook

Answer 2

factor them out? set to zero and solve for x? multiply them? you need to be specific with what to do.

Answer 3

if you're asking on how to multiply them
well, take each term on one, and multiply each term by the other
then combine their results

say for example \(\bf \begin{array}{llll}
x^2 + 3x + 4
\\ \quad \\
\qquad \times \quad 2x^2
\\\hline\\
\square ?+\square ?+\square ?
\end{array}\quad

\begin{array}{llll}
x^2 + 3x + 4
\\ \quad \\
\qquad \times \quad 4x
\\\hline\\
\square ?+\square ?+\square ?
\end{array}\quad

\begin{array}{llll}
x^2 + 3x + 4
\\ \quad \\
\qquad \times \quad 7
\\\hline\\
\square ?+\square ?+\square ?
\end{array}\)

then combine their results

Answer 4

\[(x^2+3x+4)(2x^2+4x+7)=2x^4+10x^3+27x^2+37x+28\]
=

Answer 5

@yasmin
.. yes what is the goal of this problem XD

Answer 6

Yasmin, the goal of the problem is to complete the indicated multiplication.

Answer 7

Multiply (x^2 + 3x + 4) by (2x^2 + 4x + 7), or vice versa.

The first of the 3 terms in the first multiplicand is x^2. Multiply each of the 3 terms in the 2nd multiplicand by x^2.

Next, by 3x.

Next, by 4.

Add all the resulting products together, combining like terms.
