Question

Simplify completely

Answer 1

\[\frac{ x^2-4x+4 }{x^2+10x+25 }\times \frac{ x+5 }{x^2+3x-10}\]

Answer 2

Try to factorise the expressions in the numerator and denominator. Can u plz tell me vat u get?

Answer 3

would it be 2 and 5?

Answer 4

Hmm no.
Let me show u one.
\(x^2-4x+4\)
\(=x^2-2x-2x+4\)
\(=x(x-2)-2(x-2)\)
\(=(x-2)(x-2)\)
Similarly can u factorise
\(x^2+3x-10\) and \(x^2+10x+25\)

Answer 5

lemme try the denominator, one moment

Answer 6

ha k:)

Answer 7

\[x^2+10x+25= x^2-5x-5x+25=x(x-5).... i get lost after that. is this \right?\]

Answer 8

\(x^2+10x+25\)
\(=x^2+5x+5x+25\)
\(=x(x+5)+5(x+5)\)
\(=(x+5)(x+5)\)

Answer 9

Can u factorize \(x^2+3x-10\)?

Answer 10

no, sorry, i dont understand what i would do with the 3

Answer 11

can u plz tell me two numbers whose sum is 3 and product is -10?
