WebbThe “FOIL method” is the easiest way to remember how to multiply two-termed expressions. Multiply the First two terms, then the Outer two terms, then the Inner two terms, and then the Last two terms, then sum all four to arrive at the answer: 15x2 + 10x − 3x − 2 = 15x2 + 7x – 2 Question 5 Explanation: The correct answer is (B). WebbSimplify the expression. (Assume that no variable or denominator is zero.) − 5 ( x 2 − 1 ) + 3 ( 4 x + 7 ) − ( x 2 + 26 ) -5\left(x^{2}-1\right)+3(4 x+7)-\left(x^{2}+26\right) − 5 ( x 2 − 1 ) + 3 ( 4 x + 7 ) − ( x 2 + 26 )

WebbSimplify 6 − 4 (2x + 3) + 10x. As you can see, the student somehow (at the red arrow) converted the expression " 2x − 6 " into the equation " 2x = 6 ", and then somehow "solved" the expression. But the original problem didn't have an "equals" sign in it, so there was nothing to solve! Be careful that you don't do this. WebbTo simplify an expression with fractions find a common denominator and then combine the numerators. If the numerator and denominator of the resulting fraction are both … easingwold buy and sell facebook
