## Step-by-step explanation

Problem to solve:

$\left(-6·x+3\right)\left(-6·x-3\right)$

Learn how to solve special products problems step by step online.

$\left(-6x\right)^2-6x\left(3-3\right)+3\cdot -3$

Learn how to solve special products problems step by step online. Solve the product (-6x+3)(-6x-3). The product of two binomials of the form (x+a)(x+b) is equal to the product of the first terms of the binomials, plus the algebraic sum of the second terms by the common term of the binomials, plus the product of the second terms of the binomials. In other words: (x+a)(x+b)=x^2+(a+b)x+ab. Solve the product -6x\left(3-3\right). The power of a product is equal to the product of it's factors raised to the same power.

$-9+36x^2$
