x(x + 3) + 3(x + 3)
= x2 + 3x + 3x + 9
= x2 + 6x + 9
= (x + 3)(x + 3)
= (x + 3)2
x<3 would be explained as X is greater than three. 2x+35 Would be Two Times x plus three times three times three times three times three. Actually that last one would be Two Times x plus three to the power of 5.
pover x times 9 plus power of x times 3
A number is x squared plus forty four is equal to the number x to the fourth power times three?
If that's four times x plus three, the answer is 4x + 12
x3 = x times x times x 3x = x plus x plus x
x(x+4) equals x2 plus 4x
c
Three times nine plus a number.
(x+3)(x+4) = x²+7x+12
X + 1 x X +1 = 2x + 1
6*x + 30 + 4*x = x+3; the solution is x = -3
The factors of x2 are x and x x times x plus 1 = x2 + x
