7(3y-2)-(-4y+9)

{-1,7}

It is: 9-4 = 5

It is a quadratic equation and its solutions are: x = 4 or x = -9

Using the discriminant for a quadratic equation the value of k works out as plus or minus 12.

X = √63

2 squared plus 2 x 3 = 10, 7 squared plus 7 x 2 = 63, 6 squared plus 6 x 5 = 66,8 squared plus 8 x 4 = 96 so 9 squared plus 9 x 7 = 81 + 63 = 144.

5. Just do 9 minus 4. 5 plus 4 equals 9

Solve this problem -x squared -40x- 80 =0

(x - 1)(2x - 9)

60 plus 9 plus 100 minus 100 equals 69,see 60 + 9 = 69, 69 + 100 = 169 - 100 = 69 and that is the awnser to 60 plus 9 plus 100 minus 100.

(2x - 9)(2x - 9) or (2x - 9)2

no it isnt

It is a quadratic equation and its solutions are: x = -3/2 and x = 3

Since 3 squared is 9 and 9 - 9 equals 0, that's going to be tough to factor.3x2 - 9 factors to 3(x2 - 3)

A minus and a minus makes a plus A plus and a plus makes a plus A minus and a plus or plus and a minus makes a minus 7 - -2 is a minus and a minus Therefore the answer is 7 + 2 = 9

(4x - 3)(2x + 3)

(x - 6)(x + 9)

Yes it is. The thing that makes it a quadratic equation is that "x squared" in there.

13...... 9 plus 5 equals 14...... 14 minus 1 equals 13

x^2 +8x -9 is equivalent to (x+9)(x-1) when factored

9x2 - 6xy + y2 - 81 = (3x - y)2 - 81 = (3x - y - 9)*(3x - y + 9)

9 - - 6 + 20 = 35
