(5x - 2)(x - 5)
This is an ambiguous question Ans. 1 x is an unknown. To square x, multiply it by itself x.x=x2 5 times x2 = 5x2 Ans. 2 5 times x = 5x (5 times x) squared, is (5x)2 = 25x2
5(x - 3)(x + 3)
5(x^2 + 9)
Factored, that's (x - 6)(5x + 2) x = 6, -2/5
5(x2 + x + 1)
2x2 + 5x = x*(2x + 5)
5x squared plus 33x plus 18 = (5x + 3)(x + 6) x = -6, -3/5
(5x - 2)(x - 5)
x2 - 5x = 0Factor the left side:x (x - 5) = 0x = 0x = 5
f(x) = 3x2 + 5x + 2fprime(x) = 6x + 5

5(x - 3)(x + 3)
It is: 5(x^2 -16)
5(x^2 + 9)
1. If the question is only to factor this expression:x^2 + 5x = x(x + 5)2. If the question is to solve the equation x^2 + 5x = 0:x^2 + 5x = 0 factor it;x(x + 5) = 0x = 0 orx + 5 =0 subtract 5 to both sides;x = - 5
