Answer link. 2x^2-3x-9 = (2x+3) (x-3) The rule to factorise any quadratic is to find two numbers such that "product" = x^2 " coefficient "xx" constant coefficient" "sum" \ \ \ \ \ \ = x " coefficient" So for 2x^2-3x-9 we seek two numbers such that "product" = (2)* (-9) = -18 "sum" \ \ \ \ \ \ = -3 So we look at the factors of -18.4.2 Solving 2x 2-3x-5 = 0 by Completing The Square . Divide both sides of the equation by 2 to have 1 as the coefficient of the first term : x 2-(3/2)x-(5/2) = 0 Add 5/2 to both side of the equation : x 2-(3/2)x = 5/2 Now the clever bit: Take the coefficient of x , which is 3/2 , divide by two, giving 3/4 , and finally square it giving 9/16If $(x+1)$ is a factor, then by Remainder theorem... sum of even powered coefficients is equal to that of odd powered ones... a rule to remember. $$2-3 = -5 +K ;\, \rightarrow ( K=4) $$ (BTW, if $(x+1)$ is a factor then the sum of all coefficients of a polynomial is zero.)Factor 2x^2+3x-9. 2x2 + 3x − 9 2 x 2 + 3 x - 9.

Tap for more steps... 2x2 − 3x+6x−9 2 x 2 - 3 x + 6 x - 9. Factor out the greatest common ...If a, b, and c are real numbers and a ≠ 0 then When b² − 4ac > 0, there are two distinct real roots or solutions to the equation ax² + bx + c = 0. When b² − 4ac = 0, there is one repeated real solution. When b² − 4ac < 0, there are two distinct complex solutions, which are complex conjugates of each other. Trinomial.Step by Step Solution Step 1 : Equation at the end of step 1 (2x2 - 3x) - 5 Step 2 : Trying to factor by splitting the middle term 2.1 Factoring 2x2-3x-5 The first term is, 2x2 its coefficient is 2 .
