a: what are the solutions to the quadratic equation 4x2+25=0?
b: what is the factored form of the quadratic expression 4x2+25?
select one answer for question a, and select one answer for question b.

b: (x−2i)(x+5i)
b: (2x−5i)(2x+5i)
b: (x−52i)(x+25i)
b: (2x−5i)(2x−5i)
a: x=52i or x=−52i
a: x=2i or x=5i
a: x=−52i
a: x=52i

Step-by-step explanation:

4x²+25=0

4x²-(-25)=0

4x²-(25×-1)=0

4x²-(25i²)=0

(2x)²-(5i)²=0

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

either 2x+5i=0

x=-5i/2

or 2x-5i=0

x=5i/2

i think asking google will you get the answer to that question

d) by the cross product property, ab^2 = bc multiplied by ad

step-by-step explanation:

we are given

in the given triangle abc

angle a is 90° and segment ad is perpendicular to segment bc

we can see that

triangle(abc) and triangle(abd) are similar because they have common side and same angle (90 degree)

so, triangles(abc) and abd are similar

since, they are similar

so, the ratio of their sides must be equal

we get

now, we can cross multiply

and we get

so, this could be step to prove it
