Question

(y+9) (y+9) explain step by step ​

Answer 1

Answer:

Step-by-step explanation:

(y+9) (y+9) = y(y+9) + 9(y+9)

=y²+9y + 9y + 81

= y² + 18y +81

Answer 2

• We have to evaluate the above expression by using the given data.

              Given data:- $(y+9)(y+9).$

              To find:- Value of the expression.

              Solution:-

• We know that factorization means reducing any algebraic or quadratic equation.

• Steps to solve quadratic equations,

• Step 1: Rearrange the given quadratic so that is it equal to zero.

• Step 2: Factorise the quadratic.

• Step 3: Form two linear equations.

• Step 4: Solve the equations to find the roots of the equation.

        Therefore,

             $(y+9)(y+9)\\\Rightarrow y(y+9)+9(y+9) \\\Rightarrow y^{2}+9 y+9(y+9)\\\Rightarrow y^{2}+9 y+9 y+81 \\\Rightarrow y^{2}+18 y+81.$

       Hence we will get the value is $(y+9)(y+9)=y^{2} +18y+81.$
