As written, that's 4x squared = -21 and x equals the square root of -21/4. But if you meant that to be 12x, it factors out nicely to (2x + 3)(2x + 3) and x would equal -3/2

You need to rivse your question. It appears that there is not an equation here. 4*2+12x+9? You can't really solve this it is more of a statement. You can however simplify it to 12x+17- Whoever wrote this obviously can't read. It's supposed to be 4x^2+12x+9 (2x+3)(2x+3)
