Question

Factor the polynomial completely using any method. Show steps. 2d^4-13d^2-45

Answer 1

Answer:

$\huge ( {2d}^{2} + 5)(d + 3)(d - 3)$

Step-by-step explanation:

to understand this

you need to know about:

• factoring
• PEMDAS

given:

• $2d^4-13d^2-45$

let's solve:

$2d^4-13d^2-45$

$2 {d}^{4} + 5 {d}^{2} - 18 {d}^{2} - 45 \\ {d}^{2} ( {2d}^{2} + 5) - 9( {2d}^{2} + 5) \\ ( {2d}^{2} + 5)( {d}^{2} - 9 )\\ ( {2d}^{2} + 5)(d + 3)(d - 3)$
