Which are the solutions of x2 = –13x – 4? 0, 13 0, –13

Roots are 0  , -13.

Step-by-step explanation:

Given : x² = –13x – 4.

To find : Which are the solutions.

Solution : We have given that x² +13x + 4 = 0.

By discriminate formula

For quadratic equation  a² +bx + c = 0.

= .

Plugging the values

= .

=  .

=  .

=   .

=   .

= -0.3153.

Approximate  0

= .

= .

= .

= .

= -12.68  

Approximate  - 13

Therefore, Roots are 0  , -13.

step-by-step explanation:

according to the triangle sum theorem, all the angles in a triangle must add up to 180 degrees. if we know one angle is already 90, we do 180-90=90. the other 2 angles must add up to 90, exactly.
