5x2-136 = 24 5x2 = 24+136 5x2 = 160 x2 = 32 x = the square root of 32
x = 2 or x = 2/5
5x2y = 3x - 6y 5x2y + 6y = 3x y(5x2 + 6) = 3x y = (3x)/(5x2 + 6) This is a rational function.
You cannot explicitly find the value of x without an equal sign, as an equation without an equals sign is an algebraic expression. However, we can turn your expression into an equation by adding in an equals sign, but setting the value to a variable. For example, 2x+5=y, or 5x2-4x=y. You can solve for x like that. The phrase "... there is no equal sign in the equation ..." is a meaningless description. Without an 'equal' sign, there is no equation.
5x2 - 20xy + 10y2 = 5(x2 - 4xy + 2y2) which cannot be simplified into rational factors.
5x2 - 136 = 44 5x2 - 136 + 136 = 44 + 136 5x2 = 180 5x2/5 = 180/5 x2 = 36 √x2 = √36 x = ±6
5x2-136 = 24 5x2 = 24+136 5x2 = 160 x2 = 32 x = the square root of 32
Assuming that the 2 in "5x2" is a power (5x2), then no, this is not a linear equation. It is a parabolic equation.
The question contains an algebraic expression but, since there is no equality sign, there is no equation to solve.
5x2 + 8x = 7 5x2 + 8x - 7 = 0 This cannot be factorised so the solutions need to be determined using the quadratic formula The solutions are {-8 ± sqrt[82 - 4*5*(-7)]}/(2*5) = {-8 ± sqrt[64 + 140]}/10 = {-8 ± sqrt[204]}/10 = -2.22829 and 0.62829 (to 5 dp)
X= (3/5 , -2)
5x2-8x-4
x = 2 or x = 2/5
5x2 + 12x + 7 = 0 This equation can be factored : (5x + 7) (x + 1) = 0 The equation equals zero when either 5x + 7 = 0 or x + 1 = 0 When 5x + 7 = 0 then 5x = -7 : x = -7/5 or -1.4 When x + 1 = 0 then x = -1 The solutions or roots of this equation are x = -7/5 and x = -1
5x2=10...take 5 two times..5+5=10
The value for x in the equation, 6x2 - 5x - 46 = 5x2 - 10 may be found, beginning with collecting all the terms on the right side onto the left side (after changing their signs) to result in (6 - 5)x2 - 5x -[46 - (-10)] = 0 or x2 - 5x - 36 = 0. The left side of this equation can be factored to result in (x - 9)(x + 4) = 0, which is true when either of the two parenthetical expression is 0, which in turn is true when x = 9 or -4.
(5x + 13)(x - 3) so x = either -13/5 (ie -2.6) or 3.
