Answer:
The standard form of the expression (5a+2)(a+4) is [tex]5a^{2} + 22 a + 8[/tex].
Step-by-step explanation:
Here, the given expression is (5a+2)(a+4).
Now, (5a+2)(a+4) = 5a(a+4) + 2(a+4)
= [tex]5a^{2} + 20 a + 2a + 8[/tex]
= [tex]5a^{2} + 22 a + 8[/tex]
or, [tex](5a+2)(a+4) = 5a^{2} + 22 a + 8[/tex]
Also, Standard Quadratic form is [tex]ax^{2} + bx + c = 0[/tex]
Hence, the standard form of (5a+2)(a+4) is [tex]5a^{2} + 22 a + 8[/tex].
