If you mean (4x+7)(7x+6) then it is 28x^2 +24x+49x+42 using the FOIL method
x2 + 4x - 60 factors into (x + 10)(x - 6). You can use the FOIL method to check your answers when you factor.
Yes.
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).
4x + 3 cannot equal 4x + 12:4x + 3 = 4x + 12 (given)3 = 12 (subtract 4x from both sides)
8x + 15

x2 + 4x - 60 factors into (x + 10)(x - 6). You can use the FOIL method to check your answers when you factor.
4x × 4x = (4x)² = 16x²
Use the FOIL method. (4x^3 - 4)(x^2-25) 4x^3*x^2=4x^5 -4*x^2=-4x^2 4x^3*-25=-100x^3 -4*-25=100 4x^5-100x^3-4x^2+100 Factor out a 4 to simplify 4(x^5-25x^3-x^2+25)
Yes.

If 4x-2 equals 2x-34 then x is equal to -16. 4x is equal to 2x-322x is equal to -32x is therefore -16
8x + 15
It is an algebraic expression in the form of: 4x+32
If y = 4x and 4x = 24, then y = 24 (by the transitive property of equality of the real numbers, that state:For every real numbers a, b, and c, if a= b and b =c, then a = c)
