How do you solve 2xsquared-9x equals 18?
2x2 - 9x = 18 2x2 - 9x -18 = 0 (2x - 18)(x + 9) x= -9 and 9
How do you factor 2X2 plus 9x plus 4?
(2x + 1)(x + 4)
How do you solve -9x plus 4 equals -50?
-9x + 4 = -50 -9x = -50 - 4 -9x = -54 -x = -6 x = 6.
4 9x -1 9 how do you solve this By the way 4 and 9 are a fraction so is 1 and 9?
4/9x - 1/9 is an expression, not an equation. An expression cannot be solved.
Who can factor this 2x squared-9x plus 4?
2x2 - 9x + 4 you do 4 muliply to 2 to get the factors ok which can be multiplied to give 8 and add/subtract to give -9x. OK!!!!! Factors of 8 are: 2 X 4 but it doesnt add upto give 9 so -8 and -1 give -9 when added ok!!!! 2x2 -8x -1x + 4 take common factors 2x(x - 4) - 1(x - 4) (x-4) is common so take one out and other from ooutside brackets Answer 2x2 - 9x + 4 you do 4 muliply to 2 to get the factors ok which can be multiplied to give 8 and add/subtract to give -9x. OK!!!!!

I'm sorry but I can't solve that problem. B(
How do you solve 2x2-x-3 equals 0?
2x2-x-3 = 0= 4 - x - 3 = 0= 1 - x = 0= 1 = xTherefore x = 1
How do you solve 2x2 plus 1x-3 equals 0?
2x2+1x-3=0 4+x-3=0 x+1+0 x=-1 is your final answer
2x2 - 16x 32?
2x2 - 16x32 2x2=4-16= -12x32= -384
How do you solve x2 equals 9x?
Divide both sides of the equation by x: x2 = 9x x2 / x = 9x / x x = 9
-9x5 over the square root of x plus 4?
(-9x^2/√x) + 4= [-9x^2/x^(1/2)] + 4= (-9x^2)[x^(-1/2)] + 4= -9x^[2 + (-1/2)] + 4= -9x^(2 - 1/2) + 4= -9x^(3/2) + 4= -9√x^3 + 4= -9√[(x^2)(x)] + 4= -9x√x + 4Or,(-9x^2/√x) + 4= [(-9x^2)(√x)/(√x)(√x)] + 4= [(-9x^2)(√x)/√x^2] + 4= [-9(x)(x)(√x)/x] + 4 simplify x= -9x√x + 4
