## anonymous 4 years ago Simplify: (5x^2 + 3x + 4) + (2x^2 − 6x + 3) 7x2 + 9x + 7 7x2 + 3x + 7 7x2 − 3x + 1 7x2 − 3x + 7

Factorize?

5x^2 + 2x^2 = ???

3. anonymous

$\left(2 x^2-6 x+3\right)+\left(5 x^2+3 x+4\right)=7 x^2-3 x+7$

4. anonymous

Just add them up

5. anonymous

I imagine that your goal now is make it into binomial?

6. anonymous

like $(a+b)^2$
