X^2 + bx + 49 is a perfect squad trinomial what is one possible value of b?

Mathematics
1 answer:
ddd [48]3 years ago
7 0

a perfect square trinomial, (x + y)² = x² + 2xy + y²

so, if we have the x of the bx, what is left is the b

the expression would have to be (x + 7)², since we have the 49 and the x²

so, what's left: x² + 14x + 49,

b = 14

<em>hope it helps :)</em>

5+(−4)+(−7)+2 jijujuijuijuijujijuijuijuijiji
Maurinko [17]

Combine the terms. Note that: one positive and one negative sign results in a negative sign.

Simplify: 5 + (-4) = 5 - 4 = 1

1 + (-7) = 1 - 7 = -6

-6 + 2 = -4

-4 is your answer
