Expand, answer should be a polynomial in standard form<br><br> (5a+2)(a+4)=

castortr0y [4]

Answer:

The standard form of the expression (5a+2)(a+4) is $5a^{2} + 22 a + 8$ .

Step-by-step explanation:

Here, the given expression is (5a+2)(a+4).

Now, (5a+2)(a+4) = 5a(a+4) + 2(a+4)

= $5a^{2} + 20 a + 2a + 8$

= $5a^{2} + 22 a + 8$

or, $(5a+2)(a+4) = 5a^{2} + 22 a + 8$

Also, Standard Quadratic form is $ax^{2} + bx + c = 0$

Hence, the standard form of (5a+2)(a+4) is $5a^{2} + 22 a + 8$ .
