What are the zeros of the quadratic function f(w)=2w^2+7w-4
2 answers:
Answer:f(w)=w^3 + 7/2w^2-4w+c
Step-by-step explanation:
Answer: w = 1/2 and w = -4
Step-by-step explanation:
2w^2+7w-4=0
The quadratic formula is (-b+ - √b^2-4ac)/2a
In this case a=2, b=7, c= -4
(-7+ - √7^2 - 4(2)(-4))/2(2)
(-7+ - √49+32)/4
(-7+ - √81)/4
(-7+9)/4 and (-7-9)/4
2/4 and -16/4
1/2 and -4
