5x^(2) + 15x = 0
Factor
Factor our '5x'
Hence
5x(x - 3) = 0
Hence it follows that
5x = 0
Therefore x = 0
or the other multiplicand
x - 3 = 0
x = 3
So the answer is x = 0 or x = 3 (two answers).

5x2 plus 14x - 3?
(5x - 1)(x + 3)5x2 + 14x - 3= 5x2 + 15x - x - 3= 5x(x + 3) - 1(x + 3)= (5x - 1)(x + 3)
How do you solve 5x2 equals 3?

How do you solve 15x(7-7) (5x2)?
To solve the expression (15x(7-7)(5 \times 2)), first simplify the term inside the parentheses: (7 - 7 = 0). This means the entire expression becomes (15x \times 0 \times (5 \times 2)). Since any number multiplied by zero is zero, the final result is (0).

How do you solve 5x2 equals 11?
5x^(2) = 11 Divide both saudes by 5' Hence x^(2) = 11/5 Square root both sides x = +/-sqrt (11/5) Or x = +/-sqrt(2.2) This would normally by left in 'surd' form, because the answer is an IRRATIONAL number; the decimals go to inifinity!!!!! However, per calculator x = +/- 1.483239697.....

Can 5x2 plus 2x-4 equals 2x2 be solved using the quadratic formula?
5x^(2) + 2x - 4 = 2x^(2) Hence 3x^(2) + 2x - 4 = 0 Now apply the Quadratic Equation. x = { - 2 +/- sqrt[2^(2) - 4(3)(-4)]} / 2(3) x = {-2 +/- sqrt[4 + 48]} / 6 x = { -2 +/- sqrt(50_] / 6 x = { -2 +/-5sqrt(2)} / 6 x = (-2 - 5sqrt(2))/ 6 & x = (-2 + 5sqrt(2))/ 6 Since the square root of '2' is an Irrational Number. (decimals go to infinity, the answer is left in 'surd' form .
