Question

solve the quadratic equation by factorization method 4q^2 +5q+1=0​

Answer 1

Answer:

3x2−23x+40=0

3x2−15x−8x+40=0, split the middle term

(3x2−15x)+(−8x+40) group the terms

3x(x−5)−8(x−5)=0

(x−5)(3x−8)=0, factor 

x−5=0 or 3x−8=0, zero product property 

x=5 or x=38

Answer 2

Answer:

Answer:

q ( -1/4 , -1 )

Step-by-step explanation:

4q2 + 5q + 1 = 0

4q2 + 4q + q + 1 = 0

4q ( q + 1 ) + 1 ( q + 1 ) = 0

Now

4q + 1 = 0 q + 1 = 0

4q = _ 1 q = -1

q = -1/4
