Factorising quadratic expressions maths genie
WebThe resulting quadratic expression is 2x^2+9x-5 2x2 +9x −5, and so we want to find factors of 2\cdot (-5)=-10 2 ⋅(−5) = −10 that add up to 9 9. Since (-1)\cdot 10=-10 (−1)⋅10 = −10 and (-1)+10=9 (−1)+10 = 9, the answer is yes. We can now write the middle term as -1x+10x −1x +10x and use grouping to factor: WebApr 4, 2024 · Factorising Quadratics Practice Questions – Corbettmaths April 4, 2024 corbettmaths Factorising Quadratics Practice Questions Click here for Questions .
