# Help With Algebra–Grade 9?

3 (xsquared – 3 + 4x – 3) +2 (xsquared + 5)

Favorite Answer

3x^2-9+12x-9+2x^2+10

5x^2+12x-8

well to help multipy 3 by each thing in the first parentheses. For Ex

3 x Xsquared would = 3xsquared

understand? the you would multiply the three by the other things in parentheses.

Next. you would multiply 2 by watever is in the parentheses. and then combine like terms and simplify ^_^ hope this helped. if you dont understand it still or u need more help, email me

Multiply through (distributive property)

3x^2 – 9 + 12x – 9 + 2x^2 + 10

Add like terms

5x^2 + 12x -8

Unable to factor. This is the simplest form. Doublecheck to make sure you wrote it down right. The -3 twice is weird.

(3)x^2- 3(3) + 4x(3) – 3(3) +(2)x^2 + 5(2)

Turns into

3x^2 – 9 + 12x – 9 + 2x^2 + 10

Then elminate common terms.

3x^2-2x^2-9+12x – 9 + 2^2-2x^2 + 10=

x^2- 9+12x – 9+ 10=

You can probably figure out the rest.

multiply 3 into that to get 3x^2+12x-18

do the same for the other part to get 2x^2+10

combine like terms

5x^2+12x-8
