factories: x²-x-90
fast please​

Answer 1

Answer:

x^2-x-90=0

x^2-10x+9x-90=0

x(x-10)+9(x-10)=0

(x-10)(x+9)=0

Step-by-step explanation:

Answer 2

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

            Given:- $x^{2}-x-90.$

            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,

               $x^{2}-x-90\\=x^{2}+9 x-10 x-90 \\=x(x+9)-10(x+9)\\=(x-10)(x+9).$

       Hence we will get $x^{2}-x-90=(x-10)(x+9).$
