Express x^2+8x+15 in the form (x+a)^2-b
IRINA_888 [86]
<h2>'(x+4)^2-1' in the form of (x+a)^2 - b.</h2>

Step-by-step explanation:

We have,

x^2 + 8x + 15

To express x^2 + 8x + 15 in the form of  (x+a)^2 - b = ?

∴ x^2 + 8x + 15

Adding and subtracting 1, we get

= x^2 + 8x + 15 + 1 - 1

= x^2 + 8x + 16 - 1

= x^2 + 2(x)(4) + 4^{2} - 1

Using the algebraic identity,

(x+y)^{2}=x^{2} +2xy+y^{2}

= (x+4)^2-1

Thus, (x+4)^2-1 in the form of (x+a)^2 - b.
