Using complete square to slove for x in the equation (x+7) (x-9)=25
Brrunno [24]

Answer:

x_1=1+\sqrt{89}\\\\x_2=1-\sqrt{89}

Step-by-step explanation:

Apply Distributive property:

(x+7)(x-9)=25\\\\x^2-9x+7x-63=25

Add like terms and then add 63 to both sides of the equation:

x^2-2x-63=25\\\\x^2-2x-63+63=25+63\\\\x^2-2x=88

Pick the coefficient of the x term, divide it by 2 and square it:

(\frac{2}{2})^2=1

Add it to both sides of the equation:

x^2-2x+1=88+1

Rewriting the left side as a squared binomial, we get:

(x-1)^2=89

Apply square root to both sides:

\sqrt{(x-1)^2}=\±\sqrt{89}\\\\x-1=\±\sqrt{89}

And finally we need to add 1 to both sides of the equation. Then we get:

x-1+1=\±\sqrt{89}+1\\\\x=\±\sqrt{89}+1\\\\\\x_1=1+\sqrt{89}\\\\x_2=1-\sqrt{89}
