What are the coordinates of the roots of the equation X squared plus 4X +3 equals zero

(- 3, 0 ), (- 1, 0 )

Step-by-step explanation:

Given

x² + 4x + 3 = 0

Consider the factors of the constant term (+ 3) which sum to give the coefficient of the x- term (+ 4)

The factors are + 3 and + 1, since

3 × 1 = 3 and 3 + 1 = 4, thus

(x + 3)(x + 1) = 0

Equate each factor to zero and solve for x

x + 3 = 0 ⇒ x = - 3

x + 1 = 0 ⇒ x = - 1

Coordinates of roots are (- 3, 0 ) and (- 1, 0 )

step-by-step explanation:

consider an orange peel: if you want to try and lay it flat, you have to stretch it, we know exactly how things are being stretched or squashed at any given point. we have many different map projections because each has different patterns of some projections can even preserve certain features of the earth without

students group

step-by-step explanation:

a person who   joins a party or a seminar can explain his feelings about that particular occasion better more than anyone else.

as bella managed a show for the students in the school and invited students to watch that show

hence

students group will be the best group to survey to find this information
