4 x2
It's 9 x 7 minus 2 x 7. So its 63 - 14.
x2 - 7x = 0The left side is the product of x(x-7).The equation is true if either factor is zero.So the equation has 2 solutions:1). X = 02). X = 7
"x" would equal 1 because 7/1 is 7 minus 2 equals 5 and 3/1 is 3 plus or + 2 is 5.
You find two numbers whose sum is -7 and product is +10. x2 - 7x + 10 = (x - 2)*(x - 5)

7-2x
2(x + 7)(x - 7)
It's 9 x 7 minus 2 x 7. So its 63 - 14.
x < 7
x2 - 7x = 0The left side is the product of x(x-7).The equation is true if either factor is zero.So the equation has 2 solutions:1). X = 02). X = 7
"x" would equal 1 because 7/1 is 7 minus 2 equals 5 and 3/1 is 3 plus or + 2 is 5.
2 x 4 - x = 7x
You find two numbers whose sum is -7 and product is +10. x2 - 7x + 10 = (x - 2)*(x - 5)
x/2 - 7 = -10 x/2 = -3 x = -3 x 2 x = -6
If (x divided by 7) - 2 = 6, then x = 56 If x divided by (7 - 2) = 6, then x = 30
2 x 2 x 2 x 7 x 7 = 392
