Question

(4x-3)^2 as a trinomial

Answer 1

Answer:

Down below

Step-by-step explanation:

Use the binomial theorem for the second power, which we find that:

$(a+b)^2=a^2+2ab+b^2\\(a-b)^2=a^2-2ab+b^2$

Here

$a=4x\\b=3$

we use the second formula.

So, we get:

$(4x-3)^2=(4x)^2-2*3*4x+3^2\\16x^2-24x+9$
