3p^2 - 7p -40

Factor -7 out of -7p and rewrite -7 as -15 +8:

3p^2 +(-15 +8)p -40

Apply distributive property:

3p^2 -15p +8p -40

Group the first two terms and the last two terms:

(3p^2 -15p) + (8p-40)

Factor out the GCF from each group:

3p(p-5) + 8(p-5)

Factor the polynomial by factoring out the GCF (p-5)

(p-5)(3p+8)

Ok so 3x-40=-120 and the middle number is -7 so the two numbers will have to multiply to -120 and add to - so those numbers would be 15 and-8 so then we will factor by parts so 3p^2+15p-8p-40 then section into brackets (3p^2+15p)(-8p-40) out of the first bracket you can factor out 3p and on the second bracket you can factor out -8 so you are left with 3p(p+5)-8(p+5) the combine 3p and -8 so (3p-8)(p+5)

Pls help me I am confused

Answer:

\huge\boxed{A.\ \dfrac{565}{182}}

Step-by-step explanation:

\dfrac{8}{7}-(5x-3)=\dfrac{1}{5}x-12\\\\\dfrac{8}{7}-5x+3=\dfrac{1}{5}x-12\qquad|\text{multiply both sides by 35}\\\\35\cdot\dfrac{8}{7}-35\cdot5x+35\cdot3=35\cdot\dfrac{1}{5}x-35\cdot12\qquad|\text{simplify}\\\\5\cdot8-175x+105=7\cdot x-420\\\\40-175x+105=7x-420\\\\-175x+(40+105)=7x-420\\\\-175x+145=7x-420\qquad|\text{subtract 145 from both sides}\\\\-175x=7x-565\qquad|\text{subtract }7x\ \text{from both sides}\\\\-182x=-565\qquad|\text{divide both sides by (-182)}\\\\x=\dfrac{565}{182}
