Consider the following quadratic equationr 7x 1 9Step 1 of 2 Using the standard form ax bx c 0 of the given quadratic equation factor the left hand side of the class=

Respuesta :

Solution:

Given the quadratic equation;

[tex]x^2+7x+1=-9[/tex]

Add 9 to both sides of the equation;

[tex]\begin{gathered} x^2+7x+1+9=-9+9 \\ \\ x^2+7x+10=0 \end{gathered}[/tex]

Then, factor the left hand side;

[tex]\begin{gathered} x^2+7x+10=0 \\ \\ x^2+2x+5x+10 \\ \\ x(x+2)+5(x+2)=0 \\ \\ (x+2)(x+5)=0 \end{gathered}[/tex]

ANSWER:

[tex](x+2)(x+5)=0[/tex]
