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.
