Answer:

2x² + 9x - 5

Step-by-step explanation:

Given

(2x - 1)(x + 5)

Each term in the second factor is multiplied by each term in the first factor, that is

2x(x + 5) - 1(x + 5) ← distribute both parenthesis

= 2x² + 10x - x - 5 ← collect like terms

= 2x² + 9x - 5

Can someone please help me answer this??

<h3>Answer:  x = (y-2)^2 + 5</h3>

In other words, y-2 goes in the first box and 5 goes in the second box.

=================================================

Work Shown:

y^2 - 4y - x + 9 = 0

y^2 - 4y + 9  = x

x = y^2 - 4y + 9

x = y^2 - 4y + 4 + 5 .... rewrite 9 as 4+5

x = (y^2-4y+4) + 5

x = (y-2)^2 + 5  .... apply the perfect square factoring rule

So we'll have y-2 go in the first box and 5 goes in the second box

note: One version of the perfect square factoring rule says (a-b)^2 = a^2-2ab+b^2.
