To simplify the expression ((4x - 3)(x + 5)), use the distributive property (also known as the FOIL method for binomials). Multiply each term in the first binomial by each term in the second binomial:
[ 4x \cdot x + 4x \cdot 5 - 3 \cdot x - 3 \cdot 5 = 4x^2 + 20x - 3x - 15. ]
Combine like terms:
[ 4x^2 + 17x - 15. ]
Thus, the simplified expression is (4x^2 + 17x - 15).
3x + 8
-5y2+3x+2y
Factorise it: (x + 5)(3x - 8)
5x + 4
Collect like terms: 3x - x + 4x - 4y + 6y + 2 = 6x + 2y + 2
3x + 8
-5y2+3x+2y
x^2 + 3x + 2/(-3x) - x^2 - 2=3x-2+2/(-3x)=3x-2-2/(3x)
Combine like terms. 6x - 2y +7.
Factorise it: (x + 5)(3x - 8)
5x + 4
7(3y-2)-(-4y+9)
That can be factored to (3x - 5)(3x - 5) or (3x - 5)2
Collect like terms: 3x - x + 4x - 4y + 6y + 2 = 6x + 2y + 2
This quadratic expression cannot be factored because its discriminant is less than zero
To simplify the expression 5x - (-3x), you can rewrite it as 5x + 3x since subtracting a negative is the same as adding a positive. This simplifies to 8x. So, the result of 5x - (-3x) is 8x.
You can't simplify this expression. You can calculate a value (a number) only if you happen to know how much "x" is.
