Solve the equation by factoring: x^2 + 13x = -42

-6 and -7 are the roots

Step-by-step explanation:

The quadratic equation given is:

We can factorise the equation as:

Taking x common from the first bracket and 7 common from the second bracket we get:

Taking (x+6) common from both terms we get:

x= -6 or x=-7

Hence -6 and -7 are the roots of the given quadratic equation.

x -

median = 1.25

range = 12-14.5

interquartile = q12-q14.5

y -

median = 1

range = 15-17

interquartile = q15-q17

the correct answer is 1: 2
