solve for x 2x(2) + 7x=-3 I put the parenthesis cause i dont know how to put 2x squared.?

you put 2x^2.

anyway, 2x²+7x=-3

2x²+7x+3=0, you bring the 3 to the left side. which means you add both side by 3.

2x²+7x+3=0, factor, you will get

(x+3)(2x+1)=0, now split them into 2 parts, you will get

x+3=0, or 2x+1=0

x= -3 or x= -1/2

so the answer is x= -3 or -1/2

If 2 diverse element expanded together = 0, then one or the two factors are = 0 Set each and each element = 0 and remedy for x -7x + 3 = 0 -7x = – 3 x = 3/7 a million.2x – 10 = 0 a million.2x = 10 x = 10/a million.2 = 8.333 = 8 a million/3

to be squared you should write 2x^2, ^ means u put the number higher. i forgot how to solve ones with a square lol, i did it just a few months ago in 11th grade. o well, sorry.
