Question

what is the second degree polynomials given below as the product of two first degree polynomial.

(a).
${x}^{2} + 7x + 12$
(b)
${2x}^{2} - 7x - 15$

​

Answer 1

Answer:

(a) $(x+4)(x+3)$

(b) $(2x+3)$$(x+5)$

Step-by-step explanation:

(a) $x^{2} +7x+12$   =$x^{2}+3x+4x+12$

                           = $x(x+3)4(x+3)$

                           = $(x+4)(x+3)$

(b) $2x^2-7x-15$ = $2x^2-10x+3x-15$

                           = $2x(x+5)3(x+5)$

                           =$(2x+3)$$(x+5)$
