(7x+6)(7x-6)
All three of the factors in the binomial are square roots. The square root of 49 is 7, the square root of x^2 is x, and the square root of 36 is 6. Also, since you are subtracting, you know that you will have a positive and a negative factor in the end.

Answer: An equality the state of being equal, especially in status, rights, and opportunities. Terms A common technique for simplifying algebraic expressions. When combining like terms, such as 2x and 3x, we add their coefficients. For example, 2x + 3x = (2+3)x = 5x. The distributive property It is used to solve expressions easily by distributing a number to the numbers given in brackets. For example, if we apply the distributive property of multiplication to solve the expression: 4(2 + 4), we would solve it in the following way: 4(2 + 4) = (4 × 2) + (4 × 4) = 8 + 16 = 24. Two step equations that have decimals and fractions as the coefficient of the variable and constant term are said to be two step equations with decimals and fractions. A few examples of two step equations with fractions and decimals are: 0.3 x + 2/3 = 1. 3x - 0.5 = 1.2.
