Question

Cậu nào làm giúp tớ với ạ. Tớ càm ơn nhiều ạ. Tớ đang cần gấp ạ.

Answer 1

g: \(x\left(x-5\right)-3\left(x-5\right)=\left(x-5\right)\left(x-3\right)\)

h: \(x\left(x-y\right)-2\left(y-x\right)=\left(x-y\right)\left(x+2\right)\)

i: \(x\left(x+3\right)+5\left(x+3\right)=\left(x+3\right)\left(x+5\right)\)

k: \(m\left(x-3\right)-n\left(x-3\right)=\left(x-3\right)\left(m-n\right)\)

l: \(5x-10=5\left(x-2\right)\)

Answer 2

\(a)5m-5n=5(m-n)\\b) -2x-2y=-2(x+y)\\c)-7+7y=-7(1-y)\\d)10x^3-15x^2=5x^2(2x-3)\\e) x^2-xy=x(x-y)\\f)9x^4-6x^2=3x^2(3x^2-2)\\g)x(x-5)-3(x-5)=(x-3)(x-5)\\h)x(x-y)-2(y-x)=x(x-y)+2(x-y)=(x+2)(x-y)\\i)x(x+3)+5(3+x)=(x+5)(x+3)\\k)m(x-3)+n(3-x)=m(x-3)-n(x-3)=(m-n)(x-3)\\l)5x-10=5(x-2) \)

Answer 3

giúp tớ với, tớ đang cần gấp lắm ạ.
