Question

13. Use the quadratic formula to solve the equation. If necessary, round to the nearest hundredth. X^2+3= -4x

Answer 1

a.1, 3
b. –1, –3
c. 1, –3
d. 1, –3

Answer 2

x^2 +4x +3 =0
(x+3)(x+1)=0 so here is factorized after this can you solve it easy ,yes ?

Answer 3

@jhonyy9 , they said to use the quadratic formula.
@bubble1860 , the solutions to \(0=ax^2+bx+c\) are given by the quadratic formula as follows.\[x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}\]

Answer 4

yes is right but in this way is more ,much easy ...

Answer 5

The question asks to use the quadratic formula.
