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.

a

step-by-step explanation:

the denominator cannot be the same as one of the factors.

8 denominator times 2 denominator = 16

and 7 numerator time 11 = 77

77/16= 77/16 ( they cannot be further simplified)
