Assuming you mean:(4x+36)(8x-40) = 0
then you can use the property that a product can only be zero if one of its factors is zero. In other words, you can change this to:
4x + 36 = 0 OR 8x - 40 = 0
Solve each of the individual solutions; their solutions are also solutions to the original equation.
Just one.
These are two expressions, not equations. Expressions do not have solutions, only equations do. NB equations include the equals sign.
C and D
1
Only equations usually have solutions and the given terms without an equality sign can't be classed as an equation.
Through a process of elimination and substitution the solutions are s = 8 and x = 5
None because the given terms of an expression are not equations because there are no equality signs.
It has 2 solutions and they are x = 2 and y = 1 which are applicable to both equations
Without any equality signs the given terms can't be considered to be equations.
Why are Quadratic equations, which are expressed in the form of ax2 + bx + c = 0, where a does not equal 0,
Without any equality signs the given expressions can't be considered to be simultaneous equations and so therefore no solutions are possible.
Infinite, both equations are equivalent and all possible solutions can be represented on the graph y = 4 - x
