## anonymous 5 years ago Use the quadratic formula to solve the equation..4w2+20w+25=0

1. anonymous

divide by 2

2. anonymous

wait2..its wrong

3. anonymous

Ahh nevermind.

4. anonymous

I got it

5. anonymous

(2x + 5)(2x + 5) = 0 x = -5/2

6. anonymous

w=-b+$\sqrt{b ^{2}-4ac}$2a

7. anonymous

x2-5x+14=0

8. anonymous

w=[-20+-surd(20^2 -4(4)(25))]/2(4)

9. anonymous

i dun no how to use this equation symbol

10. anonymous

Blexting! help

11. anonymous

blexting: that was factorization method

12. anonymous

Thats right though

13. anonymous

3x2 -4 +11x solve equation

14. anonymous

ya its right but you have to answer the qstn by using quadratic formula.thas what the qstn wanted you to do

15. anonymous

Thats true i dont care, we dont have to use that formula. I just want the right answer

16. anonymous

(3x-1)(x+4)=0 x=1/3,x=-4

17. anonymous

Sorry.. I was away.. do you need anything else?

x^2 - 5x + 14 = 0 quadratic formula 5 +- sqrt (25 - 4 (1) (14) --------------------- 2 5 +- sqrt(25 - 56) --------------- 2 5 +- sqrt(-31) ------------- 2 5 +- i sqrt(31) -------------- 2
