Answer:
Step-by-step explanation:
you click the first one then you click the second one then you click the fourth one
A^2 + 2AB + B^2 = (A + B)^2 ==>
16X^2 + 40X + 25 =
= (4X)^2 + 2*4*5X + 5^2 =
= (4X + 5)^2
<span>(4x + 5)(4x + 5)</span>
Answer:
Discriminant = -24
No real roots.
Step-by-step explanation:
x^2 + 2x + 7 = 0
The discriminant = b^2 - 4ac
= 2^2 - 4*1*7
= -24
So there are no real roots.
Answer:
Wrong
Step-by-step explanation:
the variable have no value and there is a new number in the second expression.
