FC: QUADRATIC EQUATIONS by Shanice Williams | q

1: A quadratic quation is any equation that can be written in the form ax^2 + bx+c=0 where a and b and c are real numbers and a does not equal 0

2: 3x+2 =7x-5 is not a quadratic because both 3x+2 and 7x-5 are linear polynomials 27a^3=9 is not a quadratic because the equation contains power of a greater than 2

3: 6x^2+5x-7=0 is a quadratic in standard form because the greatest power of x is 2

4: step for solving a quadratic equations by factoring step1 write the given quadratic equation in standard form if its not already | step 2 factor the quadratic expression into a pair of linear expressions step 3 use the zero product property to write a pair of linear equations | step 4 solve the linear equation step 5 the solution's to the linear equations are the solutions to the given equations

5: this an ex of how to solve a QE X2+3X=0 X2+3X=0 X(X+3)=0 ANS-0 OR -3 | Hope the little tips i gave you work out for you in the future
