Question

(x-7) (x-9)=195 solv the qustion

Answer 1

Given Equation is (x - 7(x - 9) = 195
 
                              x^2 - 9x - 7x + 63 = 195

                              x^2 - 16x + 63 = 195

                              x^2 -16x + 63 - 195 = 0

                              x^2 - 16x - 132 = 0

                             x^2 - 22x + 6x - 132 = 0

                             x(x - 22) + 6(x - 22) = 0

                             (x + 6)(x - 22) = 0

                             x = -6 (or) 22.


Hope this helps!

Answer 2

Answer:

The value of x is -6,22

Explanation:

Factoring provides a standard method for solving quadratic equations and complicated expressions.

From the question, we have

$(x - 7)(x - 9) = 195\\x^2 - 9x - 7x + 63 = 195\\ x^2 - 16x + 63 = 195\\ x^2 -16x + 63 - 195 = 0 \\ x^2 - 16x - 132 = 0 \\ x^2 - 22x + 6x - 132 = 0 \\ x(x - 22) + 6(x - 22) = 0 \\ (x + 6)(x - 22) = 0 \\ x = -6 , 22.$

Multiplication:

In order to find the total of two or more numbers, multiply the numbers. Multiplication tables are the main use which is obvious. Multiplication is one of the basic mathematical procedures that we do on a regular basis. It can be fractions, integers, whole numbers, natural numbers, etc. When m is multiplied by n, either m is added to itself 'n' times. It serves as an example of the fundamental idea of repeated addition of the same number. The method used to multiply integers and decimals is the same.
