Answer:

x = -7/2 multiplicity 2.

Step-by-step explanation:

 4x^2 + 28x + 49 = 0

(2x + 7)(2x + 7) = 0

This is a perfect square.

2x + 7 = 0, so:

x = -7/2 multiplicity 2.

Factor completely 2x^2 − 2x − 40.
zubka84 [21]

Step-by-step explanation:

Hey there!

Given;

= 2 {x}^{2}  - 2x - 40

<u>Solve</u><u> </u><u>it by</u><u> </u><u>using</u><u> </u><u>mid-term</u><u> </u><u>factorization</u><u>. </u>

<u>= 2 {x}^{2}  - 2x - 40</u>

<u>= 2 {x}^{2}  - (10 - 8)x - 40</u>

<u>= 2 {x}^{2}  - 10x + 8x - 40</u>

<u>Take</u><u> </u><u>common</u><u> </u><u>and</u><u> </u><u>simplify</u><u> </u><u>them to get </u><u>answer</u><u>. </u>

<u>2x(x - 5) + 8(x - 5)</u>

<u>= (2x + 8)(x - 5)</u>

<u>= 2(x + 4)(x - 5)</u>

<u>Therefore the</u><u> </u><u>answer</u><u> </u><u>is</u><u> </u><u>option </u><u>D</u><u>.</u>

<em><u>Hope</u></em><em><u> </u></em><em><u>it helps</u></em><em><u>.</u></em><em><u>.</u></em>
